Nice rig indeed and it's proven itself time and time again.WAuch,
We've had very good luck with our setup for off-road. In short, the lighter your TC, the better luck you will have over rough surfaces. Our 1998 Lance Lite 165-s, XCab weighs 1842, wet; more now I'm sure with 200 watts of solar on the roof, but not a whole lot more.
We bought it used; 3-years old and only used 3 times for $6500. It looked brand new at the time. It's old enough to have a wooden frame, which has held up very well even over rocks and down arroys. With hundreds of nights in the box, it stays on my truck most of the year and has just enough insulation to work well in summer/fall/and spring, but not below zero/F. As a former hard core rock crawler, I simply moved my technique over to the TC and made adjustments as needed. The recommendation of lowering the tire pressure on rough, slow trails is a good one. we use a speed tire deflator and a 20 pound CO2 tank with correct hardware to reinflate tires. But, mostly it's the jeeping technique that allows you to either hold 'em or fold 'em when the going gets rough.
I have no qualms about getting in the rough as the TC now has nothing to loose. I have beat this rig up mightily and it keeps popping back with only minimal TLC.
Everything still works. It has small tanks which help keep the weight down. I have traveled thousands of miles on dirt and gravel roads, adjusting the T.P. at intervals to keep the best ride and the least jarring for the TC. Here is the latest incarnation with 16 inch steel wheels:
It has taken me decades to get the truck the way I want it, and just as long to dial in all the foibles of trying to take a 10K pound beast off-road. Still, there's the thrill of seeing people's faces when you shoot the dunes with said beast; running T.P. @ 22 pounds or swimming upstream in a flash flood:
