So we bought a brand new Nash 22h last summer. Have had it out probably 15 times since then. We keep it at a storage facility when not in use. I went there yesterday and noted some bulging on the bottom of the wall on the drivers side of the trailer. There appears to be some missing caulk/sealant under there where the wall connects to the trim as well. We do live in western CO where it is very sunny and hot but not wet. Should I take this in to get fixed or seal it and then plan to cover it when in storage to protect from sun.
