Hey, I'm totally on board with a tent, heck a really nice tent is like $2K with all the bells and whistles but I can't talk anyone into it.  I've towed 6K# behind my truck in hills no problem but it was gravel, a trailer with a bunch of frontal area and a higher center of gravity is going to be more work.  I don't anticipate going very far into the mountains, probably just western NC/SC, any farther and I'll rent a Suburban or equivalent.  I really, really don't want a powered RV, just that much more to maintain.  I just found out I'd have to pay property tax on it too.  The only way I can see avoiding that is building one on my own sub-2500# trailer to avoid the legal requirement to register it at all, I'd rather avoid that though.
