[tentcamper]

I think when I read the my owner manual. It said when storing, to have the back a little lower for rain to run off the back. As other said, I think the concern is the bag seal.

I have used tarps for other campers with a support frame I built with PCV pipe. A good tarp is good for about 9 months. Just figure you need one every winter. I like the idea of a breathable tarp better then a general construction tarp.

The only thing I don't like about storing any camper outside uncovered is it gets dirty and it's hard to get clean.
