I've gone up to WV in my 28' RV and crossed creeks, single-lane dirt roads BUT was not on super steep terrain/mountains or washed out roads. The rear overhang is the issue on very rough/steep roads and can "tail drag" which can lead to serious issues especially if you can't back up to clear it! The Tiger looks great although doesn't seem to offer much more useable space than a slide-in truck camper. If you can find a reasonable used RV ($40-50k) and have it converted into 4x4 (Quigley 4x4 or similar $20-$22k) then added larger tires/front winch/lights/solar/Lithium batteries (another $6-8k) you'd be in business. I've off-grid camped in mine for 16 years now and wouldn't trade it for the world. If it's worth doing, it's worth doing RIGHT!!! Good luck!
