My family has owned everything from TC, Hybrid, Class A, Class C, and now an Open Range TT. Based on my personal experience, it is the best RV we have owned and we have tried many different manufacturers. We have only had it for 1-1/2 years but so far the only problem was a bad propane regulator which OR quickly replaced. They do come with China bomb tires so we are already looking at replacing them. I'm a big guy (almost 400 lbs.) and I can comfortably use the bathroom including the shower. The trailer feels rock solid when I move around too (none of the others did). We chose a TT over a 5er simply because of fewer steps. We went to an OR owner's rally in Texas earlier this year so I got to see many different units. There were a couple who had problems of some type with their units but they were in the minority. BTW, I have no connection to OR other than being an owner.
