The front left slide stopped working 3 weeks ago. Something appeared to be wrong with the wall but I was not sure. Yesterday I noticed the front left portion of the frame was flexing a significant amount. I started inspecting the frame and I am seeing broken welds

What component or system failed or malfunctioned, and is it available for inspection upon request? - The frame is failing. It is available to be inspected but must be inspected on site. The camper is no longer safe to drive. After we heard a loud pop when attaching to the truck and seeing the pinbox move into the nose of the camper, we don't feel comfortable moving it. How was your safety or the safety of others put at risk? After speaking to others who have this same problem, there's the possibilities ranging from exterior doors flying open during transit (stuff in our basement coming out and hitting other vehicles) to causing a major (possibly fatal) accident if the welding to the pinbox…

after pulling the camper home from a trip, we noticed that the molding was separating from the frame, after further inspection, we found that a weld was broken up on the frame that you can view from the front propane storage compartment. We contacted Grand Design and Lippert, we were told from Lippert to contact GD, we did that and GD has scheduled an SRT team to inspect our unit at the end of September. IN the meantime, we had a certified welder come and look at it and he told us it is a structural issue and he said not to pull the camper anywhere else, as it is a safety concern!! GD is telling me that they don't think it is a safety concern, but they haven't even looked at our camper.…

Our trailer is experiencing frame flex/and or frame failure. The front of the trailer is separating and also is affecting the bedroom sidewall. Also, the shackle broke and an equalizer broke. These are all know issues with Grand Design Momentums.

The frame has failed on our rv it is flexing when being pulled and we are afraid it may fail completely and break free from the pull vehicle. They are calling this frame flex and seems to be common please don't wait until a complete failure happens and people get hurt to address this issue.

MY 2016 GRAND DESIGN MOMENTUM 327M USES LIPPERT AXLES. THREE OF THE FOUR GREASE SEALS LEAKED AND WERE FOUND DURING A STATE INSPECTION. THE GREASE CONTAMINATED THE BRAKES. A 2018 STATE INSPECTION AGAIN SHOWED FAILED GREASE SEALS AND CONTAMINATED BRAKES. THE WARRANTY COVERED THE COST ON THE 2016 INSPECTION, BUT NOT THE 2018 INSPECTION. I CONTACTED GRAND DESIGN REGARDING THE ISSUE. I WAS TOLD THAT NEW MODELS WERE BUILT USING DEXTER AXLES TO SOLVE THE PROBLEM. AS A REGISTERED PROFESSIONAL MECHANICAL ENGINEER, I AM CONCERNED THAT I HAVE A CAMPER WITH A 16,000+LB GVWR THAT HAS LEAKING SEALS AND POSSIBLY FAILED BRAKES. I REQUESTED NEW AXLES, BUT GRAND DESIGN DID NOT RESPOND. I AM REQUESTING THAT…
