I've got one (a '9
and have done quite a bit of what would probably be termed as off-roading in it, getting to and from various BLM, National forest spots, etc. and have been on so-called jeep trails that are probably apply named, and have yet to break anything (knock on wood). The key is slow going. I think that Xplorer did their best to make sure that their products were capable of truly exploring, as everything is nicely tucked up in the undercarriage as possible, and although I haven't gotten out a tape measure to compare it to other designs I think that few class B's have more ground clearance. I am running 245/75's in lieu of 225/75 which does make some difference in that regard as well. The wastewater dump location is just forward of the rear wheels, and depending on how much air I have in my rear airbags is at or just above axle centerline, so is very well protected. My lowest point is the battery box; it is almost in line with the front wheel, and is very strongly built. I have scraped it a few times, but it has suffered zero damage as a result. When the going gets really rough I pump up my airbags to 100PSI from my normal 60 to 75 depending on if I'm carrying my motorcycle or not, which adds an inch or so rear clearance. And finally, the rear dually setup along with posi is a giant help, especially in mud or sandy conditions. In short, you will be amazed at how deep in the woods you can get with these things.
