Look at the chassis road clearance, especially the sewer pipes hanging down, to avoid dragging or damage on rutted or rough dirt roads with quick ups and downs. On my 2019 Wolf Pup 16BHS, I have to clear my driveway onto the highway prior to installing my WDH load bars to avoid pipe damage and cannot use my factory folding rear rack for the same reason. Added to that, the spare tire is mounted to the rack and is supposed to be able to remain there with the rack down. THAT would definitely drag!
Look at propane tank and battery mounting capacity. Boondocking, you'll likely want two batteries and larger dual tanks, along with the quiet generator or solar to recharge batteries. Using the tow vehicle for that is very inefficient. You'll use the propane for hot water, refrigerator, and some cooking. Battery for lights and control circuits for the hot water and refrigerator.
