Thanks for all the help. That link was just, that, an example.
But the good news is I just got the one I really wanted from an auction!! BOOYAA!!
Here's the one. Plus it's a big longer and I think because the roof is not as domed it's gonna be a bit taller, at least at the edges. Now I gotta figure out how to get there to get it home.
A couple of questions off the top of my head, I'm sure there are threads so I'll look later. But for now what do people think of Good Sam road side assistance. I'll be bringing this to Burning Man and want to be protected in case I break down.
Also any threads on putting a deck on the roof to hang out on? Is that advisable. As a side note I'm a lifelong metal worker and have my own machine shop so fabrication is not a problem. I was thinking of building wood ribs to fit the contour of the top, epoxy and screw them down, weather proof them then put decking material on and some collapsible railing.
