Need some quick help. I have had a leak in the living room slide-out of my 2002 Southwind 37-U since I bought it. The dealer turned out to be a joke, couldn't even get them on the phone except for the operator who put me on hold for long periods. So I finally gave up on them. Here is the problem. I have A&E Slide-out toppers on both slides. The material separated and got really raggedy looking. I called A&E and the price they gave me for OEM was ridiculous. So I went to an Umbrella Factory and they are making me new toppers for almost half the price. The material is acrylic, very strong, and water resistant. Also matches the paint colors on my motorhome pretty good too. I want to fix that pesky leak in the slide-out while I have the topper material off. They have rubber roofing material on them but evidently the water is getting through it or around it. What do you recommend that I coat the roof with to seal it. When I first bought the motorhome all the screws had the heads broken off on the trim piece along the outside edge of the slide-out. I fixed them and put Devcon caulking under the trim. But that didn't solve the problem. If you need further clarification or have a quick solution please e-mail me at: email@example.com. Your help will be greatly appreciated. Oh, and the dealer was Walt Michael's Stupor Store in Belleville, Michigan. Avoid them.
