JEEP 1/4-TON TRAILERS
 

1942 Willys MBT Jeep 1/4 ton Trailer

Jeep Trailers
There are 4 models of what are commonly referred to as Jeep (cargo) Trailers.

  1.  The WWII Military MBT and T-3 Jeep Trailers
  2. The Post-War (WW2) Civilian Jeep Trailers
  3. The Korean War vintage M-100 Military Jeep Trailers
  4. The Vietnam War era M-416 Military Jeep Trailers
Willys MBT Trailer Data PlateThe 4 Jeep cargo model series are very similar in design, size, and construction.
All 3 Military Trailer series share the following characteristics. Differences between the 3 military jeep trailer models include: Here is a photograph of a WWII  Jeep and Jeep Trailer.
Here is a photograph of a Korean War M-100 Jeep Trailer.
Here is a photograph of a Vietnam War M-416 Jeep Trailer.

M416's are the easiest to find.   They are also the newest and in the best shape usually. Here is another Photo of a M-416B-1 Trailer - Side View. Notice the gas can racks on the sides. This is the M416B1 model.
The WWII is the next most common (even so, it is still rare), but it can cost a lot more because there is more demand.
The least in demand, and slightly harder to find M100 is my 1st choice for the average person with a civilian jeep.  If you are just looking for a great looking, great off road, great on-road trailer to haul a motorcycle or lawnmower then please leave the pristine antique trailers to the collectors. Hauling a motorcycle would require cutting a tailgate (losing the water-tightness). Hopefully you will find a civilian trailer or one that is already cut, and not ruin an intact army trailer by cutting it.

Expect to pay between $465 and $900 for either a M100 or M416 trailer. The Willys MB-T & T-3 Bantam Trailers can go for more money. It depends on the condition, and the part of the country you are located in. And remember it is Willys, not Willy, Willis, Wilys, or Willies. Bantam, not Bantem, Bantum, or even Batman.  :-)

WWII Military Jeep Trailers - The Willys MB-T & The Bantam T-3 Trailers ~ History, and model differences
Willys and Bantam (and a few others) made nearly identical trailers in World War Two. Officially it is the 'TRAILER, AMPHIBIOUS, CARGO, 1/4-TON, SINGLE-AXLE'. Here is a Photo of Two original WWII Jeep Trailers (Front 3/4 view). These jeep trailers were used increase the payload hauling capacity of the jeep. The jeep trailers could haul food, ammo, fuel, people, medical supplies, clothing, bedding, and all sorts of other supplies. It was common to see these trailers in the field overflowing with supplies & equipment as in this photograph of a WWII trailer.  The Jeep Lube Chart issued late in the war had the lubrication chart of the Willys MBT/Bantam T-3 Trailer on the reverse side. Photograph of Original WWII MBT (MB/GPW Jeep on reverse) Lubrication Chart. Willys-Overland produced nearly 60,000 of their Model MBT trailers. American Bantam produced 73,569 of their version of the Willys Model MB-T trailers, the Bantam T-3. There are subtle differences between each company’s version. The some of the trailer design differences are listed below.

1/4 ton Bantam and Willys trailers (MBT / T-3) used the same type of black out lights as the WWII Jeep. However, switching between normal and blackout lights on the jeep pulling the trailer did not affect the status of the lights that were running on the trailer.  The trailer had its own light switch mounted to the front passenger side box frame. Here is a photo showing the small WWII MBT Jeep Trailer B/O Light Switch mounted in the front of the lower passenger side. There was a small disc (door) that swiveled out of the way to reveal a small set screw that can be turned using the butt end of the Jeep H-700 Key to switch between running lights and B/O lites.
Here is a photograph of the Jeep's Trailer Socket & Cover on the back of a WWII MB/GPW jeep (where the Trailer's Cable plugs into).

These trailers were also amphibious! They were designed that way. The trailers could be floated across streams by themselves (without a jeep or other vehicle) either by having soldiers wading alongside them or by using ropes from both shores tied to the trailer. The trailers were designed to also be towed behind 2 amphibious vehicles - the Studebaker Weasel, and the amphibious jeep - the Ford GPA - both in and out of the water! Here is a photo of the Ford GPA towing a WWII Jeep trailer full of GI's in deep water. Another photograph showing a Ford GPA towing and swimming with a Willys MBT 1/4 ton Trailer while the trailer undergoes floating tests from 6/15/1942. Notice the date. It proves that water operations were intended from very early on.

Where do I find my WW2 Jeep Trailer's Serial Numbers?
The Willys MBT and Bantam T3 Trailer serial numbers are usually difficult to locate. MBT's and BT-3's had trailer (vehicle) Serial Numbers stamped in 2 places.

Locating Serial Numbers on Second World War Willys MBT and Bantam T-3 Trailers

  1. THE DATA PLATES ON THE FRONT BODY PANEL

  2. The data plates is found on the front panel of the trailer, facing the outside. It is on the drivers side close to the outside top.  It is held in place by 4 screws or 4 rivets. The data plates are often missing. The Nomenclature plate has the vehicle identification information including; the Manufacturer (Willys, Bantam or other Co), the Model (MBT or T-3), the Serial Number, and the Date of Delivery (Date of Manufacture). This is the actual trailer manufacturer serial number. These Data Plates were made out of Brass, Pot Metal, Steel, and Aluminum. Be very careful removing paint or straightening dents on your data plates because valuable information about your Jeep Trailer can easily be destroyed in the process. There were 4 versions of the text on the Trailer Data Plates. Two each for Willys and Ford. Two each Early QMC, 2 each Late ORD.

  1. THE FRAME

  2. The frames for trailers were also sometimes stamped. One source of of stampings are from ACM, the manufacturer of the body tub/frame unit that all the companies built their trailers on. Another souce for some of these stampings are from rebuilders. Typically there are 3 places to look on your trailer frame.  See pic below to help you in locating the areas to look in.

    Location #1 & #2  may have the rebuild serial numbers stamped into the outside face of the frame in approximately 3/8" high numbers. Location #1 & #2 are not factory locations for stamping the serial numbers.  It appears that the military stamped the numbers there on some trailers to make it easier to determine the serial number.  Many trailers that went to the PTO (Pacific Theater: Japan, Korea, Guam, Philippines) came back with numbers stamped in the alternate locations. These could have been stamped during the Korean War, or Vietnam War or ?

    Location #3 is UNDER the trailer. This is the ACM serial number. The ACM serial number was stamped directly into the frame or support bracket. Bantam trailer ACM serial #'s start with a "B". You will have to crawl under the trailer, lay on your back, and look up at a triangular piece of metal bracing the frame. This brace is about 5" x 6", and the ACM serial numbers are stamped into it. The number is stamped under the left front spring hanger bracket on the frame.

    Serial numbers located in #1 & #2 should match data plate serial number on the body. The serial number in position #3, is the Tub Mfg.'s (ACM) number, and not the Trailer Serial Number. The numbers are closely correlated. Closely, but not exactly matched. Mr. C. Lutz is keeping a database on the relationship of these two serial numbers.

    When I go looking for serial #s, I use a propane torch and a small wire brush (toothbrush size). These items are the best I know of to help in locating the Trailer frame stamped serial numbers because there is usually some grease, rust, dirt, and old paint to deal with. Hit the area with the torch until the paint bubbles.  Then scrub with the brush. WARNING: The hot melted paint will fall all over you, so wear old clothes and eye protection!! Re-apply the heat and scrub till you get to bright shiny metal, and hopefully a serial number. Sometimes the numbers are very faint, in fact, the whole stamping can be very light, so some care and good lighting will be required to uncover it.

    Here is photograph on where to look for military trailer stamped VIN #/ serial numbers. They could be stamped in any of the 3 locations, or none of them.

Post War Civilian Bantam T-3C 1/4 ton Jeep Trailers

After the war, Bantam struggled along for a few years manufacturing 1/4ton Jeep trailers (T3C) for the civilian market. This kept the company alive, but only barely. In the end it wasn't enough and Bantam finally went out of business after just a few more years of trailer production. Bantam's civilian T-3-C trailers were stripped down copies of the Military MBT/T3 Trailer without all the features that the military trailers (T3) came with. Bantam went on to produce this basic trailer after the war for the civilian market from 1946 until 1953.
     Although they weren't a completely new design, the trailers were given the new model name: BT3C. (They are also called BTC, B-T3C, BT-3C, BT3-C, T3C, T-3C, T3-C by others. A long list to describe the same trailer). Bantam also added some features that civilians would find useful, ones that the military would have objected to. They added stake pockets to the T3-C, so you could put wooden stake sides (to haul more cargo) and/or wooden top bows (to hold a tarp up) on the trailer. They discontinued the parking brake assembly.  No brake drums on axles, and no hand brake ass'y. The lunette eye style receiver was replaced with a civilian type ball hitch receiver. The data plate size was reduced in size to 1"x3" for most of the civilian trailers, although some early ones did come with full size 3"x3" plates. The data plates were mounted in the same place as the military trailers - towards the top of the front panel on the drivers side. These smaller data plates were only held on by 2 rivets instead of 4 rivets. Originally these smaller plates were closer to the top of the top rail tubing, but they were eventually lowed a few inches more down the panel. Civilian trailers came with fewer rope hooks / cargo tie downs (for securing a cover tarp, or tying down the load it was carrying). Military trailers have 4 per long side, the civilian T3-C trailer only has 3 per side. Both Military & Civilian trailers had 1 hook tie down on the front & rear panels. A dropping tailgate was added and the rear section had reinforcement gusset panels added to support the body & tailgate. The tailgate was not wanted on military trailers because military trailers could float. A tailgate would not allow amphibious use of the trailer by the Army, Navy, and Marines. It would, however, add a lot more usefulness to the civilian customer by making it easier to load & unload things for the trailer. The gusset panels were needed to compensate for the cargo body's loss of strength when the tailgate was added to the trailer to prevent flexing and too much stress being put on the body panels and welds. These panels were the new location for mounting the rear reflectors and taillights. If the new T-3C came with tail lights, they came with civilian taillights instead of military black out lights. The front panels of trailers with no taillights would have been issued without the extra upside down rope hook to hold the vehicle electrical cable when not in use - no taillights, no need for electrical inter vehicular cable, no electrical cable, no need for a hook for it. The side red reflectors of WWII were discontinued as well, and the rear red reflectors were moved from the rear body panel to the outside tailgate reinforcement gusset plate panels. The major changes made to the BT3 for conversions to the BT3-C in the civilian market are detailed below.

How to tell if you have a Bantam Civilian trailer.

  1. Look for 'stake pockets' inside the trailer on the long sides of the cargo body wall to allow mounting the cargo body top bows.
  2. Look for 3 rope hooks / cargo tie downs on the side of the cargo body. (Military Trailers have 4 hooks / tiedowns.)
  3. Look for only 2 rivets or rivet holes where the data plate would mount on the outside front body panel, drivers side, towards top. Keep in mind that some early trailers did come with the 4 rivet 3" x 3" data ID plates. Most civilian trailers had the 1" x 3" data plate.
  4. Look for a lack of parking brake, brake drums, and brake cable assembly.
  5. Look for a lack of side reflectors on the rear side 1/4 panels.
  6. Look for a Factory drop down tailgate & side gusset support plate panels at the rear panel. (NOTE - Many military trailers have had tailgates hacked into them. Most were done very poorly). This meant they were no longer water tight.
  7. Look for a Factory civilian ball hitch receiver. Hitch is a Fulton Standard 1 7/8" Ball type. (NOTE - Many military trailers have had civilian ball hitch receivers hacked/welded onto them. Most were done very poorly).
  8. Look for a smaller civilian style electrical connector plug and trailer cable. (NOTE - Many military trailers have had their original Heavy Duty cables & Plugs removed and replaced with after market civilian ones. Most were done very poorly).

In 1946 Bantam trailers were available from the factory in Butler, PA in Red and Green paint colors only. The suggested retail price in November 1946 was $169.50 plus $8.12 tax for the basic cargo trailer. The Utility Chassis (no cargo body, wiring or fenders) was $126 plus $6.62 tax. Side Racks, Bows and Tarpaulin Set was $35 plus $1 tax. A flat tarpaulin was $12 plus $.38 tax. All prices were F.O.B. .
 
 

Other Countries Copy the American 1/4 ton Jeep Trailer.
The World War II Trailers were also copied by several foreign counties during the cold war era. There are some subtle and some not so subtle differences in these foreign manufactured jeep trailers. Differences such as lighting, brakes, and in the number of reinforcing ribs pressed into the floor and side panels of the trailers. Japan, and Switzerland both made copies. The Dutch and French Armies each had their copies as well. WOF (Willys of France) made some of them, as well as GENEVA, MILLION-GUIET, and HOTCHKISS. Many of these French 1/4ton Jeep trailers had front mounted spare tires (as seen here and here and here and here) and are still the companion of the PEUGEOT P4 today. Canada has made a copy the M416 trailer, called the M101 CDN, and has really beefed it up and added some really nice features as well.

Converto produced around 6,500 1/2 ton trailers during World War Two. These Airborne Dump Trailers had similar dimensions to the Bantam T3 1/4 ton jeep trailer, and used Kelsey-Hayes MB/GPW jeep combat wheels that had been reinforced with metal plates to make them stonger and able to carry a heavier load than the standard World War Two Jeep Trailer.  http://wwiijeepparts.com/WW2/Photos/19411942194319441945MilitaryJeeps/ConvertoDumpTrailer.jpg

K38 / K-38 Linesman Trailer
Here is photograph of a K-38 Jeep Trailer Model.The K38 Linesman Trailer, also called the Telephone Cable Splicer 1/4 ton, Single Axle Trailer for Equipment TE-56, was used by both the civilian telephone companies and the military in daily service before, during, and after World War Two. The trailer in Military use was called the G529 K-38 ¼-Ton Trailer. The K-38 was a very small covered box trailer that was used in the military prior to WWII until about the end of the 1950's. It was utilized most by the US Army Signal Corps, and by similar units in the AAC / AAF, USMC and USN. See CONSOLIDATED SUMMARY OF MAJOR ITEMS OF EQUIPMENT : (Signal Requirements for Complete Project). dated 1 Nov. 1944 ~ item #47 <see 3 items above "Page 2 of 6 Pages EXHIBIT 3G">.  It is basically an Off Road Tool Chest on Wheels. It has a lift open metal top, and a lower pop open cubby hole at the rear. It used 16" tall motorcycle tires, had heavy-duty leaf springs, and a lunette eye and two loop pulling handles on the front of the drawbar. Taillight, folding landing leg, and padlock hasp to protect the contents were all standard issue, as was a rear work shelf. When you flip up the lid (passenger's side opens, hinge is on driver's side), the inside is full of tray compartments for tool and equipment storage. The 'Military Telephone man' would draw a jeep & K38 trailer from the motor pool and go out for as long as necessary to run communication lines between units. These trailers were made in far smaller quantity than regular jeep box trailers, and these trailers seldom come up for sale. Data plates were mounted on the front body panel in the lower driver's side corner. They were made by at least 4 companies over the years;

  1. FWD Auto Co., Eagle Division, Appleton, Wisconsin (data plate).
  2. York Hoover Body Corp., York, Pennsylvania
  3. Highway Transport Co., Edgerton, Wisconsin
  4. Transport Freight Co.

How the M416 is different from the M100;

There are at least 2 M-416 trailers that have been modified into a power driven trailer. I do not know of a single instance when the military might have done this. Take a M151 rear axle and add it to a M416 trailer. The driveshaft runs from the jeep to the trailer, and the trailer's wheels become drive wheels, giving you 6 wheel drive with one point of articulation. The Vietnam war era Jeeps, the M151 series jeeps, have a unique differential pumpkin with a yoke on both sides of the case housing.  This allows a second driveshaft (PTO) to come out of the rear of the jeep's differential and extend to a pivot point where the trailer meets the jeep at the pintle hook. Another driveshaft continues from the pivot back to the trailer's (M151) differential yoke.

I have heard of one guy in the late 1980's who added the differential to his trailer, added a permanent articulating driveshaft, and drove around in 6 wheel drive. Eventually he got pulled over for running the jeeps license plate on the back of the trailer and not registering the trailer. He went to court saying it was now all ONE vehicle and therefore only needed one registration.  The Judge agreed based on the driveshaft power driving the trailer. It made the news, but I never heard anymore about it.
 

M716 / M762 Small Generator Trailer
These flatbed trailers are based on the M416 chassis, and are rated at 3/4-ton gross. The TRAILER, FLATBED, M-762, have the same shape flat fenders as the M416's have, but these fenders also have the interior (or back side) closed off to prevent water from splashing onto the load. These panels are also needed to support the fenders since there is no body to mount them to the side of.

Re: Dents in a trailer bodies floor
Recently a  US Army soldier stationed in Alaska wrote me about a rough M100 trailer he had just purchased.  The floor - as so many are - was caved in and dented.  So I emailed back a old school tip that I was told about 20 years ago.  Thought I might as well post it here as well.
Locate a 6x6, 8x8, 12x12,  etc. piece of wood.  Cut it the exact height as the distance between the top of the rolled edge of the trailer and the floor of the trailer (or where floor should be). Flip trailer tub upside down over the standing up piece of wood (you might have to add side legs or flat base to wood to keep it standing).  Keep repositioning the tub dents over the wood and hammer the dents from the top.  Re: hammering - With propane torch heat the edges of the dent, then hit with hammer.  After doing this a few times you have stretched already stretched metal.  So now heat the dent in the middle and after getting it nice & hot toss a cold wet rag on it.  This shrinks the metal back.  Repeat until dent is gone or greatly reduced. Move on to next dent.
Re: Backing up a trailer
I have heard some people say "the trailer was of very limited use, because you just could not back it up more than 10 feet before it jackknifed.  And it was impossible to predict which direction if you started by backing straight."
That is absolutely not true.  I can back any of my 5 military jeep trailers, loaded or empty, straight backwards at a fast rate with no trouble at all.  I have had doubting Thomas's before, and have on several times hit over 20 mph in reverse (clocked by a following vehicle).
Yes, there is a 'trick', that was taught to me by an old motor pool Sgt.
The 'trick' doesn't make sense, and I was a 'doubting Thomas' myself... until I saw it with my own eyes.  Then I did try it, and dang'ed if it didn't work.
No the trick is not "Steer from the bottom of the steering wheel in the direction you want the single trailer to go." (If you really have a hard time or it's your first time backing up a trailer, then you might want to try the "hands at the bottom of the steering wheel" trick until you become more proficient at the maneuver).
Although I have heard that this helps people who have a hard time conceptualizing how to position trailers... It has nothing to do with the trick I am about to go into.

Ok here’s the trick.  Use it in moderation. Jeeps, Trailers, horses, airplanes and lots of other things can be dangerous to operate. Caveat emptor, and I take no responsibility if you crash, get cancer, or are attacked by terrorists, or anything else bad happens to you.

When backing up, rock the steering wheel back and forth from left to right.  There is a certain cadence that you will get the hang of.  You want to turn the wheel enough so the truck/jeep just starts to rock slightly - the same way you would rock the car going forward when you were young and driving was fun LOL.

The gist of it is that the trailer lines up (but doesn't turn) to go to the left, and then it gets pressured to re-line up to go to the right, just in time for it to be pressured into getting realigned for a left turn...  and so on and so on.    This constant "left push, right push, left push, etc." keeps it straight online.

It's sounds weird, But it works.
