Here's a low budget Hauler Project my son and I put together. I actually have this posted on Pirate 4x4, http://www.pirate4x4.com/forum/showthread.php?t=480067
but thought you folks might be interested. It's a 7.3 ltr diesel retired Uhaul. It's not fancy, but it functions. We have made the 1200 mile R/T to Tellico with no problems. AC, full 120 volt and 12 volt systems, 1500 w inverter, water tank, water heater, grey water tank, work bench. overhead storage.
Doors and windows from an RV graveyard.
Interior 'living quarters:
back section. The bi fold doors have to be open to fit the jeep inside. 4 9000lb. tie downs bolted through the frame.
Out door Bubba shower with hot and cold water.
Dash mounted monitor to keep an eye on the jeep inside and a camera mounted out the rear to watch the jeep on a trailer.
Tellico trip/Crawfords Camground
One jeep inside and one on a trailer!
And just so the neighbors know what it is for:
It's been a blast to put together. The air suspension drops the truck down 4" and some ramps do the rest. There is another Uhaul conversion project going on at the Pirate Board also (guy named Yager, doing a great job!)
