“The front of our grand design momentum fifth wheel camper has sustained some structural failure. Our bedroom slide will no longer stay closed when driving down the road. Our storage doors will also open every now and then when we encounter rough bumps or rough roads. We began to notice some small damage inside the front bedroom of the unit as well.
