and here's what I know.
Well made, pulled nicely even when I tried some gravel back tracks.

Hardly knew it was there even at the gas pump [only lost about 1/2 mpg].

Steel frame, under coat is some type of plastic cloth

Windows and doors fit and work great!
Side walls a anodized al over 3/4" luan plywood walls [7 layers I think].
I'm adding vents, electric inlets, porch lights, a box on the front and some lights on the hatch so far

Other wise just camping and planning what to do with the inside. Being only a 4 footer there isn't much room for bells and gadgets in the galley but the planning is fun. Any ideas out there are welcome.

I'm sorry I'm flying to Fl next week to see my Sis, I'd almost rather be here working on my TD.
I want to have everything done but the last week in July for a trip to the Rockies for a photo workshop.
I'll get some pictures up tomorrow.
