So it's in progress. It's a smaller one based on my 5x10. I'm trying to build it light, so she can pull it with just about anything. The 3/4" plywood skeleton walls are being cut. I picked up some 3/4" EPS foam last weekend.
Tony helped me with my 1st build through this forum. I think he used the term overkill a time or two.

Pictures to follow...
