Our frame on our 2022 Grand Design Solitude S Class 3740BH has failed. While towing this RV 5th wheel trailer, we have observed signs of frame flex/failure and now it has been verified by RV tech Justin Douglas of TBD RV Repair out of Denver, IA 319-883-6030. Items to note: Our hitch inbox appears to rise and fall several inches during transport. The front cargo doors and side entrance door have opened during transport after being secured. Several pieces of moulding have aœpulleda out from shifting along the front trim of the trailer. The afore mentioned left and right sidewalls appear to shift during transport resulting in pulled screws that support the bedroom floor connected to the sidewall. The roof membrane has separated at the front cap from shifting back and forth. We believe theyare maybe be structural damage to the roof and front chin cone as well under the membrane but we have yet to open the roof to protect the rest of the trailer from rain. Cabinetry in the front bedroom has shifted causing separation of the shelves. The thin staples keeping the particle board have fallen back into the front cone. We re-secured them so we could use the closet without items falling into unaccessible parts of the structure. The bedroom and master bath floor squeak and rise and fall (move) when walking on them The bedroom door has also gotten stuck closed after transport due to shifting. The right side leaf spring compensator (CRE device) was cracked from what was believed to be from lateral shifting and was replaced. No lamps or warning messages were applicable for this problem. The police have not been involved at this time nor any insurance as of yet. We feel that if these items are not immediately corrected by Grand Design, this may result in a safety risk on the road.
