Newbie need help with purchase decision

I wouldn't think there is any HTT that wouldn't be able to be set up while still hooked to the TV. The bed can't come down any lower than the propane tanks, and I doubt it would extend past the hitch. I overnighted in mine numerous times w/o unhooking when we had a HTT.

Also, if the OP is looking at bringing adult guests I would think they would be infinitely more comfortable in a HTT bed than in a TT small bunk bed or dinette.
