corner leaks

I also use PolySeamSeal White to recaulk my Pod.  After carefully removing the loose caulking, I use a small rag with 3M General Adhesive Remover #8984 on it to clean the area.  8984 is about $10-15 a quart but lasts for years (available at most auto-parts dealers and auto-paint stores).  You only need a small amount on a rag to clean.  It is used to remove decals from clear coat paint.  So it is safe to use on the Pod. Don't let it dribble onto the Pod's decals...8984 is designed to help loosen decals!  It also removes 99% of dried-on bugs.
Loose or cracked caulking can accumulate dirt in the cracks. Caulking needs a clean surface to adhere to. Polyseamseal seems to withstand rain and heat-cold better than any other caulking I have used. I also agree that silicon-based caulking is a poor choice for repairs.  Once the silicon is on the Pod, it does not allow you to re-caulk well later.  I think that the silicon leaves a coating on surfaces which inhibits adhesion when you try to redo it. Silicon caulking also seems to attract and hold road dirt tightly.

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.

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.
