What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Front of 5th wheel movement caused by excessive frame failure, inspection shows 1/2" out of compliance. Lag screws around interior upper deck backed out and have to be tightened regularly, soft spot in floor between bathroom and upper deck bedroom. Additional body screws needed in garage area to hold skin in place.
The contact also stated that the failure had caused the seal around the bedroom window to become defective. The RV was taken to an RV dealer for repair. The contact sent several letters to the manufacturer about the failure.
Moisture has reached electrical wiring, creating a serious fire hazard and contributing to unsafe living conditions. Essential componentsâincluding the furnace, refrigerator, and water heaterâhave proven unreliable or unusable throughout the ownership period.
This constant overload is only leading to a fire hazards. This is yet another issue and example of potentially life threatening the RV industries refuse to make right.
Our inverter and battery switch caught fire during a camping trip 8/12/24. My family was put in harm's way with the possibility of the trailer going up in flames! Called Grand Design. They immediately made a ticket for a technician to come replace inverter and other wiring.
The contact stated that while driving uphill at 65 MPH and depressing the brake pedal, the trailer brakes failed to respond as needed. The contact pulled over onto the side of the highway and was able to bring the trailer to a complete stop. No warning lights were illuminated.
We heard a clunk, thinking it was a blowout I checked the rear view mirror only see the tire (drivers side rear) rolling away from the vehicle. We immediately pulled over to the side of the interstate and further inspection found the disc rotor hub/spindle missing from the ale.
On this RV the back man door will not close/latch. We have to use a bungy cord to keep it closed. The latch on the door doesn't catch on the wall catch plate.
