We love our Open Range (see signature) and have used it a lot. Many miles of towing with insignificant problems. I did have a cabinet come loose (not off the wall but pulled away) and fixed it myself. I did not have to take it to dealer at all for warranty work (they have a two year warranty). Only thing I had done during warranty was they gave me a new propane regulator when the original would not switch between tanks. I don't plan to outlive my current Open Range but if I do I would definitely buy another one. There are a lot more 5ers than TTs but we chose the TT to avoid interior steps.
