We have replaced all the furniture in ours over the years. Added a third captain's seat and two Lazyboy recliners, a desk and a small chest of drawers. Easiest was the slide side as you can just run it out to get underneath to get to the bolts. The other side you need to reach/crawl into the basement compartments. Leave all the seat belts in place-you'll need them over time. Be certain you bolt/screw things back down one way or another. We left the recliners loose, and just use the seat belts to hold them down when traveling.
