I just bought a Forest River NoBo 10.6 and after getting it home and really going thru it, I have to say that it is pretty cheap in quality as well as price. Forest River gets their frames from Lippert and and mine looks to be about 14 guage, or .078 inch...pretty thin stuff. I was lead to NoBo for the "off road" design, but I'm skeptical now after having it and I'd say it's pretty limited and even some of the not so well maintained BLM roads would be a bit much for it.
I jumped on it because of the price, but now I'm regretting it. I had it 3 days and had to send it back for warranty repairs and its been at the manufacture for 3 weeks now and they still haven't gotten around to looking at it yet. The NoBos look cool, but I'd read customer complaints before purchasing one. Check out this link....I found it AFTER buying...
