We have a 2014 Bounder 33C. We have 33K miles on it so far. We have been from FL to Alaska and crossed every mountain chain in between. We have done long 9 percent grades (towing our jeep) up and down, taken it to 11,000 feet, and gone 'off road' with it. We live in it full time and have 0 complaints about our bus.
We have looked at other RVs since purchasing our Bounder (I think RV owners are required to) but we haven't found anything we like better. Ours is holding up well, has the perfect floorplan for us, and does everything we have asked of it. The only thing we would consider changing is the flooring. We hate the carpet.
We are in Salisbury Beach right now if you have any specific questions.
