I have a couple trailers we built that are going out as rentals, one is the off road rv you guys have seen, and the other is our combo toy haulers/ice shack. The toy hauler fits a tracked side by side, good for hunting or going quadding, has a furnace, stereo, lighting, 2 bunk bed cots, etc. The RV has a fridge freezer, hot water, charge system etc, queen size bed. The RV can go just about anywhere, it's built for off road.
The RV is $100/day, the toy hauler is $150/day. Pics attached.
