Just did that exact thing. Removed the jackknife sofa from the slide area, removed the dinette table/benches, and the recliner behind the passenger's seat. Put in new flooring...carpet squares from "Flor." Replaced the dinette with a Futon-like sofa that worked out perfectly! We got the new sofa at World Market...this one...
We used "L" brackets and screwed the sofa to the floor. So far so good and everything rides and looks great. It was amazing how much more room we gained by removing those items that, honestly, we never used. And we shed quite a bit of weight by getting rid of them too!
