This is my fourth ex-military truck. It’s a 1970 Kaiser-Jeep M109A3 2.5-Ton 6×6 Shop Van. I bought it as a replacement for my first military truck, which is also an M109A3, but which needs a lot more cosmetic restoration.

I sold this truck in September, 2005, and I’ve preserved the for-sale listing because it has lots of good pictures of the truck.

thumbnail Safe and sound in my driveway, a few miles away from the unloading point. I told my neighbors that it’ll only be there temporarily. Only time will tell if that was an accurate statement… 🙂

thumbnail Here I am picking up an AN/GRC-122B radio teletype (RTTY) system mounted in an S250 shelter. Part of the deal was that I had to take the 1.5-ton trailer that the shelter was sitting on. I probably will mount the shelter on my HMMWV eventually, and then sell the trailer. The March ARB airfield is in the background.

Van Conversion Pictures

Here are some pictures of work-in-progress on my conversion of this truck to a camper/radio truck. I’ll update these pictures and/or move them to a different page later.

thumbnail I replaced the original 120VAC 60A Arktite connector with an 120/240VAC 60A IEC-309 pin and sleeve connector. It has the same mounting bolt pattern as the original connector, but lets me deliver twice as much AC power to the van body. I’ll paint it to match the vehicle later. I’ll replace the cable with a larger one later; this one lets me plug the van into a 120/240V 20A outlet in my garage to run the lights and outlets in the van while I work. This picture also shows part of the copper fuel line for the van body heater.

thumbnail Here’s the fuel pump for the van body heater. I’ll fabricate a cover for it later.
5/1/02
thumbnail Here’s a view of the left side of the van body. I’ll put a self-contained porta-potty in the left rear corner, under the ventilation blower. This picture shows the laundry tub that I’m installing, and the twin-size bed, mounted on a pair of lockers for storage, with a pair of 36-gallon water tanks underneath. I’ll mount a refrigerator, microwave oven, and additional storage under the bed, in between the lockers.
5/1/02
thumbnail Here’s a view of the right side of the van body, showing the two-story 10 foot wide by 2 foot deep workbench I installed for radio gear. The workbench tops are 1-3/4″ thick solid maple butcher blocks. I haven’t installed any radio gear yet. The big box with two meters on the floor is a PP-4763A 28V 50A power supply, and the silver toolbox (which I may paint later) contains a pair of 12V Optima deep-cycle batteries.
5/1/02
thumbnail This picture shows the AC power boxes. I kept the original switch for the AC lights, but replaced everything else. Also shown are my home-made control box for the fuel-fired heater and a circuit breaker box for power from the vehicles 24 VDC electrical system.
5/1/02
thumbnail I didn’t like the way the original AC wiring was done, so I removed the original harness and re-wired everything with surface-mounted conduit.
5/1/02
thumbnail This picture shows the PP-4763A 28V 50A power supply (which is mounted on equipment slides so it can be slid out for service), the battery box, and a junction box which allows the batteries to be charged through blocking diodes from various sources, including the power supply and the vehicle’s 28 VDC electrical system. The batteries supply power to all of the 28 VDC accessories (including most of the radio gear) in the back of the van.

Timeline

6/13/2001 My truck arrives from Maryland.
5/6/2002 Lately, I’ve been working on converting this van into a combination camper and radio truck. Of course, this isn’t a “correct” configuration! I still have a lot of work to do, but things are starting to get interesting…
9/14/2005 Truck sold. I realized that I wouldn’t use it as a camper/radio truck I intended to, because I don’t like driving big trucks that much.

  1. how much it it all cost to get it done?

    • If my memory is correct, I paid $6,500 for the truck, plus another $5,500 to have it shipped all the way across the country from Maryland to southern California. I did not keep track of what I spent on it after that, and I sold it for a lot less than I spent on it.

  2. Hi, I’m building an in scale model of the M185A3, and I have to build by myself the shop van, the model is in 1/35 scale I need please the dimensions of the little window on the sides, possibily also the position.
