We took delivery of a Flagstaff 8528RSWS which is the sister of the Rockwood version.
Just finished a 2082 mile, three week trip with just a few minor problems which I was able to fix. Two things yet to be fixed, the bottom seal on the shower split and one of the led bulbs in the hanging ceiling fuxtuer went bad, blowing the 15 amp fuse.
DW and I are very happy with it so far.
