Owner report 11570026 · 2024-02-05 (February 5, 2024)
We have frame failure on our trailer, we have not taken it apart yet to give all the details on the welds broken but metal is starting to come out from the fiberglass, and our cabinets inside came part. We contacted Grand Design and they stated as second owners there is no warranty, we contacted Lippert they said to reach out to GD and our insurance said they do not repair manufacturing issues. We will be taking to a shop at the end of February and will have a better understanding of all the issues.

Owner report 11654890 · 2025-04-16 (April 16, 2025)
I started noticing rub marks on the interior walls next to the night stands after the last few uses, and they appear to be getting worse after each use. I was made aware of the deck/frame flex issues the some GD fifth wheels are having and was referred to TSB 24-001. My RV is experiencing the exact concern described in the TSB. I opened a case number with GD, and took the RV to an authorized repair center. The repair center took measurements and confirmed my deck flex concern with GD and recommended a complete replacement/repair of the struct…

On the driver side of the 2018 Momentum Toy Hauler cracked in two locations above the center leaf spring holder. This issue occurred on May 1, 2025. While pulling out of a shop after having the leaf spring holders replaced the axle traveled through a small depression on the ground causing the frame to flex and make a loud enough sound to be heard in the truck pulling the camper. While investigating the situation it was discovered that the frame cracked at the weld points of the gusset bracket that was attached to the frame. The owner of Haw…
