....one thing I forgot to mention: early on when I 1st found water in the battery and propane containment canisters, I thought about why I had not ever seen water in these places before.
I came to the conclusion that a) we were only camping ~3 times a season max since 2010, so never had a need to look in/open the hatch but for 3 times a year; b) the water that was flooding in probably drained right into the camper structure and disappeared perhaps over a week or two.
So, a thought would be: even though we may not find water in these containment centers today, water could be getting in there during rains, draining quickly into your camper structure, and the left over film of water on canister floor is drying very rapidly (between rains)....hmmmm?
