The big question swirling around in my head though is just how capable are these trucks when it comes to offroading beyond the graded dirt roads? Are they top-heavy? can they flex well enough with that much weight? are the trucks still within their GVWR?
Top heavy isn't an issue for us with our XP. The GRP/carbon fibre structure is very light, and although the tankage is massive it is all located low down. The camper is solely mounted to the flat bed which enables a degree of independent flex. Certainly the cab can adopt a slightly different angle to the camper at times.
Here's us completing a lap of the White Rim Trail (Canyonlands NP). We were the first vehicle to make the trip after the first snow in Nov 2012.
We were complete offroad novices 3 weeks prior to this. Yet the XP V1 coupled to a lightly modified F350 gave us enough confidence to tackle this ascent, and the tighter scarier one on Hardscrabble Hill.
In the preceding weeks we drove out to Racetrack Playa and over Hunter Mountain in Death Valley NP, and crossed the Grand Staircase Escalante from Escalante to Alstrom Point via the Hole in the Wall, Left Hand Collet Canyon and Smokey Mountain Road. This summer we also completed the ascent/descent right to the shoreline of Laurel Lakes nr Mammoth.
Regarding the opening to the elements when raising/lowering this hasn't ever been an issue for us, although admittedly we haven't camped in a really buggy area. But we did full time for 5 months ski camping (Tahoe/Aspen/Utah/Jackson/Whitefish/Revelstoke/Whistler). The dual top ran continuously from early Jan until mid April (15 weeks) without a fault - no need to enter a cold camper after a long drive. Many nights in negative numbers (farenheit) but plenty warm enough; I've managed an interior temp of 91f with the Webasto thermostat at 80% whilst outside it was in the 20s!
