Link will take you to the Forest River website page for both the Flagstaff and Rockwood models. Click on either Falgstaff or Rockwood and then Floor Plans and you can see the different models along with the traditional soft pop ups. There are not a lot of differences between the Flagstaff / Rockwood brands, what drove me to a Flagstaff is it is the brand sold locally to me.
My wife and I just took delivery of our T21QBHW yesterday. Before deciding on it I did a lot of research, in this forum and a couple others, and we looked at Aliners and the Flagstaffs. I liked some of the Aliner features but they are significantly more expensive than the FR models. After our looking and doing more reading we went for the T21QBHW as it is ideal for
our needs.
