Well, you have the rig to haul most any TC you would like to.
Camping solo, pretty much any TC is big enough for 1 person.
That said, features vary by model and mfg and while we camp with 4 people and a slide out is a bonus just for space, you may not need that and can get a comparable non slide for less $ than a slide out.
The other features I honed in on were tank size. If you're boon docking, more water capacity is better, fridge size. Not much room for coolers so it's a great convenience to have all the cold good in the fridge and a separate freezer. Generator is a must for us. Pros and cons with built in vs separate. Noise in the camper, ease of service and propane use being the downsides for me with a built in unit.
Location, as you may be aware, TCs are pretty scarce on the east coast, maybe an excuse for a road trip! As for care, I'd pretty much only look at older TCs that I could reasonably ascertain had been stored under roof or at least a cover for most of their life.
Good luck in your search, their dime a dozen out here, alot to choose from. If you can't find what you want back east, might have to take a road trip!
