I used to have an OutdoorsRV Backcountry (their bunkhouse entry level trailer). The quality of the OutdoorsRV trailer that I had was outstanding. I now have a Desert Fox by Northwood and I can honestly say that the quality in construction of the Backcountry was or seemed at least to be better than that of the Desert Fox. I did not have one issue at all with the OutdoorsRV trailer whereas I have about 5 current issues with the Desert Fox. FYI if you don't already know is that OutdoorsRV is owned by Ron Nash who is the owner of Northwood. Both plants are located in La Grande, OR. The OutdoorsRV uses the Northwood chassis (good thing) and are fantastic 4season trailers. I wouldn't hesitate one bit to get a Blackstone.
Good luck on finding a dealer though. It would seem that you'll have to travel quite a bit to the North to get one. Closest seems to be in Wyoming or Utah.
