I thought about it for a while...it would of been a way to give extra protection against branches when off-roading, and so the cover doesn't get weakened over time from the sun. I thought about doing it in fiberglass, and maybe even integrating LED lights on it. It wouldn't be hard. Make a wood frame of the dimensions and form of the tent, wrap that in foil, then follow your form with a cloth/absorbent material, attaching it as little as possible to remove it from the frame later, then you coat that in resin. The fiberglass resin doesn't penetrate paste the foil, so your form won't stick to the frame when you want to remove it. It's a similar process I've seen done for custom speaker boxes, but I've done the form/foil trick on my own FB projects. Once that's done, you start putting on layers of FB cloth to thicken and strengthen the form.
My big question was what do I do with it when I'm setup at the site? Do I incorporate holes for poles and it turns into a makeshift shelter to cook under?
