Finally made it by an auto parts store today, and bought a big tire innertube. Got it all cut up, and made my piano hinge gasket.
I also went to the box store and returned everything I didn't use, and bought some things I didn't get enough of in the past. Had to get more 90 degree aluminum to make drip rails above the windows. Also while I was there I needed to pick up some a new shovel. I walked through the plant section and notice hanging plant hooks, that mount to an eve, or post, and swing back and forth. Bought two of these to mount on the exterior of the camper to hang my Dietz lanterns from.
Tomorrow it heads to storage for a few days to get it out of the way, and so that I can take care of a few things in the yard, (meaning it is housing inspection time Monday, and it needs to be out of site

).
P.S. It has rained on and off for the past two days, and still no leaks!
