Ok; Fairly well into my build, (finally), and have a very few pics to post for ridicule, if you're so inclined. Also a bit of an attempt at using something out-of-the-box for skinning mine.
Started with a self-built frame of 2"x2" box tubing rescued from the scrap dumpster at work, with locally sourced spindles and hubs. Frame is 5'x8', and the walls are 5'x10', allowing a 12" overhang front and back. The overhang areas will be utilized as storage in the rear, with cubby-holes front, accessible from the cabin area. There is a bit of (currently) wasted space lower and upper in front. Walls are 1/2 ply, spline jointed in the center to make the 10' length. (Could only get 5'x5' locally, and that from my former employer.)
Without further boring ado, I present;
