What owners report
Frame flex frame has unbolted from inside of travel trailer on upper deck bedroom walls falling off
I'm submitting this report on our RV because we are discovering we very likely have an issue with the frame which is causing over flexing when it is being towed. This has caused damage inside the RV where the trim and cabinetry are damaging the walls due to more movement than should be occurring. We have notified the manufacturer, Grand Design, for guidance as we've read this could be caused by broken welds in the frame. They requested we send them photos which we have but are still waiting for information back from them. At this point we are concerned that the RV may not be safe to use until we can discuss in more detail the issues we are having and how they can't be fixed if possible. W
Our camper has frame flex. We opened a claim in October 2025 with Grand Design. Received a letter stating they would cover any repairs. It's been in the shop now for over a month and they keep telling us the claim is "in review". Our upper deck frame is cracked/broken, our walls are separating, the door opens when we are traveling down the road. The roof is falling apart, bubbled and cracking. Side walls are cracked. We've sent pictures, the shop has sent pictures and we are getting no answers. The newest they are telling us is that it's now out of warranty. The camper isn't safe to tow and they aren't fixing it or providing the shop with details on how to fix it.

The condition is further degrading the safety of the unit with each use in transit.
