The units that Super Dave posted were pulled behind the 2.5 ton trucks and I wouldn't recommend it for the same reasons he mentioned. When I was home on R&R earlier this month, my wife and I took ours out camping near the Chattooga River. I don't have any photos of the rear but we cut the back and created a drop-down tailgate. It's a great rig as long as we stay out of the hot and humid weather....which almost eliminates any thoughts of camping in July and August in the southeast unless you're in the mountains.
Here is one in Texas for $1500.
