I just had a roof inspection done by the dealer since our unit is new. Had an area that needed some work done so while it was there I had them do that. I like to keep as much as possible documented during the warranty process so I let the dealer do it. I used to climb on the roof and sweep off before retracting slide outs but with the new 5th wheeler, I had toppers put on all the slides. Pushing 70 real close now and the wife says I just don't need to be on the roof anymore. I tend to agree with her! Makes a much happier household!
