We have the 24FBS, which is very similar to yours, but a bit longer and we have a slide (where the dinette goes out). We really enjoy that the couch faces the TV area and certainly ours has lots of storage.
As others have said, we have the Denver "pillow-top" mattress and its nothing to write home about. We bought a nice memory foam topper from Costco and it made a world of difference.
Enjoy your new trailer!
