It is a bit ad-laden, but this "camper" has a lot of options that would work in a Traveller universe:

from the article (I've bolded a couple of things that I thought was interesting):
What you wouldn’t expect from a typical RV, however, is the Unimog’s insane off-road prowess. Aside from the extreme ground clearance, the full-time AWD system has low-range and diff-lock capabilities for accessing areas well-and-truly off the beaten path. In fact, the vehicle has up to 140 on-board functions – one of which includes a hydraulic four-point lift system to remove wheels if necessary – and it’s all touchscreen-controlled inside the vehicle. It can carry 211 gallons (800 liters) of fuel, which is enough to give this uber RV a ridiculous range of over 2,100 miles (3,500 kilometers). There’s also room for 227 gallons (860 liters) of water, and with options like winches and chainsaws available, occupants in the EarthCruiser Explorer XPR440 can get seriously lost if they so desire.
