So does mine. How is the sealant that overlaps the cap to the roof? I'm having issues with mine and looks like I'll be replacing the roof very soon because of it.

It seems that some roofing membranes are not chemically compatible with current lap sealants. When these sealants are used on some new membranes, bloating and disfiguration of the membranes results. If you have purchased a 2011, 2012 or later RV model you might want to be aware of this when doing significant repair work that involves resealing the roof membrane. I'm not looking forward to having this done as this is going to cost me an arm and a leg but it has to be done since I have experienced water intrusion.
