I've seen a mod on a Casita
17 Spirit (side dinette) in which swivel chairs were mounted on the dinette bases. I don't know if Scamp's is big enough to do the same.
But since you have layout 7, what about the front sofa? Is it being used for something else? With the addition of a throw pillow or two, I find the angled backrest very comfortable for lounging on the front sofa of my Scamp
13, and the cushions don't slide around like they do on the dinette. (Storing the banana cushion on edge behind the backrest increases the angle slightly, a little trick I learned from this forum.)
