I am writing to formally report a series of serious structural concerns we are experiencing with our Grand Design Momentum 349M fifth wheel/toy hauler, which appear to be related to excessive frame flex/failure or upper deck instability. These issues began toward the end of last year and have progressively worsened, raising significant safety concerns for our family. The following symptoms have been observed: * Bay and Propane Doors Opening During Transit Both the bay door and propane doors on either side of the trailer have opened unexpectedly while towing on the highway, posing a major safety hazard. * Loud Cracking Sounds from Front Driveras Side Wall We consistently hear loud cracking noises from the front driveras side wall during towing and hitching, suggesting structural stress or movement. * Exterior Trim Separation The exterior trim pieces repeatedly separate during travel, despite multiple attempts to re-secure them with bolts. * Cabinetry Movement in Front Cap Sleeping Area Most concerning, the cabinetry in the front capa”where our 8-year-old son sleepsa”visibly shifts forward and backward during towing and hitching. This movement is both alarming and unacceptable from a safety standpoint. We have documented these issues with photos and video evidence, which are enclosed with this message. Please ensure the volume is turned up when reviewing the video to hear the structural noises clearly.
