Cool, thanks, guys! So, nobody's worried about stability?
I'm going to start modding my H12 as soon as I settle on attachment strategy (velcro, etc.). I think maybe I can assemble the entire thing myself with velcro, and a short stepladder. The top piece is challenging, but could maybe be velcroed from the inside, with tape handles inside the top piece to pull on to get enough pressure. For rain proofing, maybe attach a small nylon skirt to the top piece, that flops over the edges of the adjoining pieces, maybe weighted. Elsewhere, orient the velcro seams to keep out rain. Also maybe velcro the tarp to the bottom edges. I have to figure out the roof-section hinge parity, and play with the model to convince myself I can attach it to the walls edge-by-edge, without assembling the roof as a unit first. Placing the roof on the base of the H12 took four of us.
