I can see this might appeal to some. The price seems pretty reasonable and it would be great for the backwoods types who are thinking their tent is getting a little old. For myself, who defines roughing it as "not putting up the satellite dish", it is not going to appeal!
I'm thinking that once he sells a few, his technique will develop and things like wronkles will disappear. I wonder if he might have trouble gettinh into some campgrounds due to the rustic/homebuilt appearance.
