We have the swivel rockers in our HT 26.5 RLS and just slide the driver side on close to the door. Have found on four different trips that they don't move. Can still get into the FW, even with the slide closed and the chair moved over. Unfortunately, FW is just a little too short in the rear end for the chairs to just sit where they are when bringing the slide in. Our couch has some straps to secure the chair on the couch when traveling, but that seemed like a lot of work so we just move ours a little bit. They aren't very heavy.
