corner leaks

Welcome.  It absolutely shouldn't be leaking.  Is yours still under warranty?  If it is, have the dealer look at it.  If you are going to look at it you need to peel off the rubber gasket that runs along both edges and look underneath.

David, how do you tell if the seam needs a touch up?

Bad news is... I'm longer under warrantee and the camper is permanently located 1000 miles from the dealer I purchased it from.   Reason for storage is that, contrary to dealer assurances, it weighs more than my Dodge Caravan can safely handle, even with a tow package.   Good news?   It rained quite a bit today, with no evidence of moisture.   Seems it only happens during really torrential rains.   I'm looking into having someone inspect my rooftop vents, etc. to begin with.

Originally posted by David   I go all around the camper and look at all of the seams - corners, around windows, porch light, door, compartment doors, etc.  If I see that any of the caulking/sealant has pulled away from one or both surfaces, I'll repair.  Even small leaks can cause big damage over time.   I hope to get out soon and start working on mine.  If I find something that I can get a good picture of, I'll take one.   On my Pod, after one season, one window and the porch light needed repaired.
