We were faced with the pop-up, A frame, or TT dilemma, so we went to the RV dealers and settle on a TT size we thought we would like. We own an old pop-up so we know what they were like.
Once we found the size we liked (24 to 26 ft.) with slide we rented one for 10 days.
Pulling one of these barns down the road was an education. My old 200 hp. truck was under a real strain in the hill of the Ozarks and it gives you a new appreciation for stopping the load.
We had fun but it was a learning experience. In the end we bought a new truck and TT.
