John, I own a BR 3705BH. It is a very nice camper and we are finally enjoying it. However, the first six months after I bought it new we had a lot of trouble with it. There were a lot of QC issues from the factory. My dealer has got it mostly ironed out, but we had a host of minor problems and a few major ones, from a busted black tank to loose wiring connections. We haven't had any new problems this year and have thoroughly enjoyed it. Keep in mind that folks who have had problems are always the most vocal.
Blue Ridge and Cardinal are sister units, so you might want to check with some Cardinal owners as well and see what their experience has been. The BR has a lot of storage, which is what sold me on it over the Keystone Montana. Now that most of the kinks are worked out, I hope to have it for several more years. It is perfect for us, but there were a few months that I'd have liked to have parked it on the desk of whomever is responsible for Forest River QC.
Good luck with your decision. I hope whatever you choose gives you many years of happy camping.
