2 years ago we purchased a '98 Mini Winnie in very good condition. Before I bought the unit it always was stored inside. We do not have that luxury. Shortly after we bought the unit, we noticed a couple of roof leaks. After much looking (they aren't easy to find) we found one in the skylight above the shower, and another that was actually through the holes the clearance lights mount above the front sleeper loft. I cleaned off the old sealant and resealed them with silicone as best I could. It appeared to work all through last season. Now, however, we have leaks in the same two areas. Is there a better procedure to fix these kinds of leaks? I am afraid I am going to get some more severe damage if I don't put an end to these leaks.
