Body and structure: “Upon returning from a most recent trip we started to notice significant floor noise, moving interior cabinetry, and a cracked front cap on our 2023 Grand Design Momentum 395MS-R.

During the time at the dealer, an SRT from Grand Design was on site and was actually the one to perform the inspection and supposed repairs. …”

Suspension: “My fifth-wheel trailer is subject to NHTSA Safety Recall 26V-044 involving the axle U-bolts and leaf-spring attachment system. The recall repair was performed by an authorized Grand Design dealer. After the recall-related condition/repair, I discovered a broken bolt in the rear suspension/shackle-hanger area and abnormal/uneven tire wear. I returned the trailer to the authorized dealer because of concern these conditions were related to the recalled suspension system. …”

The RV was in the shop from Jan-May 2023 to address this. Had the doors replaced and resealed. They still are not flush with the RV, still barely latch, and have popped open while driving. While in the shop, they addressed but could not duplicate the underbelly continuously filling with water when it rains. …”
