So these aren't just for foamies, but I figured I'd drop them here anyway.
1) Use an existing plastic or fg lid or covering, filled with foam (spray foam), for a hatch or door. There are golf carts where I work and I keep looking at the "roofs" on them (~3'×5') wondering if one could fill them with foam for rigidity and use them for a small pop-up roof or a covering for solar panels etc. Also, same theory, a lid from a plastic trash can for the same purpose. Getting bigger, a lid for a big dumpster (about 5'-6' square) with the same treatment. They even have provisions for hinging.
Be honest with me. Does this idea stink?
2)Use the top forward section of a 5th wheel for a small camper. I see them on Cl sometimes for free or real cheap. I can't help but visualize what it would look like to cut the bottom off and set the rest of it on a 12'-16' trailer (trim the back end off to fit, of course). Not sure about the old ones, but the new ones have a single piece of fg (or plastic) for the nose. Very aerodynamic and professional looking.
3)Could one use a small dehumidifier for an ac unit in a td? Thats what ac was originally designed to do & I think the smaller size would be just right for a td.
4)Would it be feasible to use some aluminum channel of various shapes (H, F, W etc) for joining walls to floor or ceiling to walls or floor to trailer etc? It might be cost prohibitive, but just wondering.
I think that's all for now, but I'm sure I forgot a couple. Please let me know if they've been tried or if they are unworkable ideas.
