Hi, We're Jeff and Joyce and we are new owners of the 16 foot hybrid (S16H) out this year. We really enjoy camping in the hybrid. When we first got the camper, it was all over the road behind our suv. We had it towed back to our dealer and called Cruiser RV immediately. The manufacturer got with the dealer and they found that the wheel had no bearing. It was fixed that day and the manufacturer also gave us a friction bar which was very good service. Our problem now is we just completed a 1,500 mile trip and the unit can't get over 60mph. It shakes the wheel and you are forced to slow down. Wind conditions and you're down to 45 - 50. It's very annoying. This is our third trailer and we're not at all satisfied. We called the manufacturer during the trip but have not gotten a reply. Tonight we're going back to the dealer and will see what recourse we have. We didn't realize this was a "park model". Will keep everyone informed of the outcome.
