Slide roof sagging in the middle.
I have a 2017 Denali 287re and been noticing my slide sagging in the middle. I came home last night from work and noticed trimming damp and saw water dropping. The dealership replaced the floor back on the slide in September, but couldn't find what caused the floor to be rotted out.
Just wanting to know what the fix would be. It looks like it needs a support beam in the center.
I did purchased this used from the original dealership it was purchased from as well I'm the second owner.
