I have one that used to look like that. Only paid $200 for it. When I finished restoring/rebuilding it, it some how looked like a teardrop. The problem I ran into was when I removed the alum skin, the sides fell to the ground.
Remember 'Teardrop Time'.......Take your time, you don't have to have it finished NOW.
Somebody posted one on Craigslist today up in Cottonwood for $100, but said not to bother to call if you couildn't be up there within an hour. Cottonwood is more than an hour away, and I was at work...
