Bill G and I began work on an old teardrop trailer I bought. It has a three battery solar setup, air-conditioning and a one ton frame. Problem is the guy who built it put the trim on sand caulk so the walls rotted. We are building new walls out of fiber glass coated plywood. I will post pictures of this 'Barth-lette' soon. If anyone has any ideas that might help, please let me know.

Thanks
