What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that while driving 50 MPH, two of the passenger's side windows detached and started flapping against the RV wall. The contact veered to the side of the road, and duct taped the windows to the side of the RV.
Floors in bottom storage bays are sagging and bowing are at risk of failing out on high way. Need to be replaced with better material .
Fortunately, the exhaust system was cold at start up, but had it been in running for a while and went into in regeneration mode, a fire could have resulted considering the fine mist that was being sprayed onto the exhaust. I immediately remove and replaced the filter the next day.
