I disagree with the no OD advice. That depends on the transmission design. There are plenty of vehicles and transmissions that can happily tow in OD.
This is a thread that goes to a daydream I have every year. I see it as having a two-part RV. Part One is used for driving around, and Part Two stays at the camp site. And Part One has some minimal RV facilities. This is where the dream becomes fuzzy. Trying to decide which functions to duplicate in both parts, and which functions are exclusive to just one.
Functions:
Transportation (for how many?)
Rest room
Sleeping
Kitchen
Lounging/ Living Room/ TV
There are places to buy small TT's or toyhaulers anywhere from just a bare shell inside, to fitting them with various RV components. You just have to decide which of the above functions the trailer must do.
I think I'd like the trailer to be the living room, kitchen, dry bath. It should have A/C. Maybe a furnace, maybe not. A nice sofa, an easy chair, television, and eating area. But no beds.
And pull it with a cargo van conversion with the basic floorplan of the Winn. Travato 59K (shown below). The van would have only a cassette toilet or possibly a plumbed toilet with minimal tankage. No kitchen except a plug in cooler. Two good twin beds as shown. Heating and cooling. This would be the camp's bedroom, and would be a great touring camper as well.
