I know some people who swear by them, and wouldn't buy anything else. I have to say, I have been nothing but impressed by Open Range. Their floor plans are unique, which I love. I don't see many TTs, mostly 5ers.
I can't speak to build quality, as I personally have never owned one. They will however be high on my list when I look to replace my current TT.
