In reading about peoples' experiences with the Skyshed, it seem like there are issues with leakage around the base. Since I'm planning on building a deck platform for it (maybe 2' high), which will be over ground that is frequently damp/wet, I'm also concerned about excessive humidity rising off the ground and migrating through the spaces in the deck planking into the POD.
To try to reduce these problems, I was thinking about the following as a possible design. Basically, the idea is to us a layer of plywood as a base on top of the deck planks. I would put a plastic sheet over that, which would extend out onto the deck planks around the edge, and then be covered by some vinyl cove moulding like this stuff: http://tinyurl.com/cqkhe9r I'm thinking the plastic would be a humidity barrier, and raising the whole thing by the plywood thickness would keep water from migrating under the bottom of the POD wall because it would have to go uphill to get in.
For people with experience with the POD, what are your thoughts about this design? Are there things I'm not considering that could cause problems? Thanks!
