We purchased our 2021 Grand Design 395M Momentum new in early 2021. Over the past year we noticed cabinets on the passenger side bedroom separating from there wood frames. We initially repaired the cabinets ourselves thinking it was just poor workmanship. This last trip from Houston to Myrtle Beach the cabinets again separated. Someone in the campground at Myrtle Beach informed us about the issue with Grand Design’s frames. Upon closer inspection I noticed that the bottom of the cap had separated approximately 1′ and when you lower the unit onto the 5th wheel hitch the pin box sinks an additional 1.5′. It appeared sever enough that we were uncomfortable towing the unit back to Houston. We secured an enclosed trailer (at our expense) for our items and left the unit in storage (at our expense) until we could contact Grand Design. We contacted Grand Design and are scheduling our unit to be towed to a local Myrtle Beach dealer for repair. In my opinion if we would have attempted to tow the trailer it could have broken loose and collapsed on to our truck or broke free entirely. At a minimum I do believe a letter notifying owners of the issues is warranted and what repairs/changes are being made. It is only a matter of time before there is a catastrophic event with sever injury or death.
