Frame failure issues diagnosed on the camper in 2023. We were not apprised of how serious the frame failure was or provided photos of the issues, so we are not sure how extensive the issue was. Repairs were performed by a Grand Design dealer prior to the Technical Service Bulletin being released by Grand Design. The repairs being performed prior to the TSB leaves us somewhat skeptical that they were performed according to Grand Design engineer specifications. Post repairs, we have had some of the same symptoms recurring again (sawdust after every trip, furniture movement, garage wall separation, front cap filon separation, door opening during travel (previously reported to the federal safety agency), indicating that perhaps the frame issues are persisting or recurring.
2020 Grand Design Momentum body complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
11/15/2023: Kitchen slide of the RV partially opened while traveling down the road. My husband does have video of this occurring as we have a camera system installed on our RV. 6/25/2024: Kitchen slide of RV "raised up" and landed on an island drawer pull while traveling down the road. The slide could not be "lifted off" of the drawer pull and we were forced to activate the slide and allow it to travel out, causing damage to the drawer pull and drawer rails.
Back door of RV came opened while driving down the road. The door is always locked (dead bolt included) and the entry-assist arm folded over the door during travel. Upon parking for the evening, it was noted that the back door of the RV had popped open during travel.
Excess frame flex. Contacted Grand Design, they scheduled an inspection and then preformed followup repairs. New bracing and support were added by Grand Design.
My grand design had the have frame flex fixed twice and it’s still not fixed correctly. None of the aluminum behind the cap was fixed as grand design didn’t want to fix it and lippert would on touch the steal frame.
We noticed our pin box on our GD started moving when we hitch up. The wall inside the bedroom is showing wear from movement, the trim around the upper deck came apart multiple times, the flooring inside the bedroom had a hole in it from the bed gouging into it. When hitching up the wall is bulging out on driver side just off of the slide corner. Our slide stopped working and there are Gibs inside the wall of the slide that had sheared off rivets.
I have had front flex on my grand design repaired twice already and it’s still has issues. They didn’t weld any of the aluminum back together they would only do the frame, my bedroom walls and cabinets wouldnt get fixed either because that’s cosmetic.
The front area where the pin box connects to the truck has multiple welds are breaking on the structural frame causing these trailers over flex while driving down road. There has been multiple cases of the front deflection being out of spec on multiple trailer. With these welds broken it can cause the trailer to separate where the truck would hook up to the trailer and if the concern is not addressed.
The contact owns a 2020 Grand Design Recreational Momentum. The contact stated that the floor was started buckling and there were bubbles on the flooring of the trailer. The contact stated that one of the bubble was near the front bedroom towards the bathroom, and the other bubble was towards the hallway. The contact took the vehicle to the local dealer however, the mechanic was unable to identify the cause of the failure however, the mechanic was willing to fix the esthetics by sanding the floors and replacing the linoleum. The trailer was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 1,000.
