It sounds like you’re on the right track for what you want to do. I agree with other posters, go to an RV show and look at a lot of TT’s before you commit, though. I use a TT that would work for you, 16’ and 3000# loaded. And I camp well back in off the pavement sans tv’s, generators, and other amenities of the big units. But it doesn’t have the dry bath which has never been an issue to me. Otherwise it has everything I need to camp.
I would add as much ground clearance as possible and sturdily built for the rough roads you’ll likely travel. I haven’t kept up with the market, but I’m a fan of Northwood, they’re built for off pavement. I think Lance would qualify and probably others also. Other posters more up to date can likely add some other possibilities.
