We are on our second Flagstaff, which is the twin to the Rockwoods. They are built in the same plant by Forest River and differ only cosmetically and model numbers. Floor plans and construction are identical.
Our first one was a 26RKS model which we really liked.We had it 10 years before trading it in on our current model, a much larger 35' 831FLSS which we got last year.
Overall we had very little problems with the first one and none with the current model we have. Of course we have only had the current one a year but kept it at Myrtle Beach the first 6 months we had it and spent quite a few nights in it then.
We have found the Flagstaff to be of good quality construction and would not hesitate to buy another one, (or a Rockwood model) although this one will have to last a long time!:)
