Wing- IMHO, you shouldn't let anybody named Mike in your coach. Results will be bad newz to start, then comes the real trouble.
That PS floor issue is one to watch. The floor is a vacuum bonded assembly, about an inch or so thick (not the 2" of the coach floor). I believe the interior floor edge is an aluminum tube, and there is a plywood top sheet and foam core. The deflection appears to spring back out every time, although there will always be a bit of sag at least due to the weight of the recliner. If you were to drop a heavy load on the middle edge of the slide when in (e.g. some big guy named Mike), you might put a bend in the tube and create problems for actuating the slide. The bend could be reversed by prying up from the floor, but that's only a solution if needed.
From an engineering standpoint, the flush-floor design either requires a thicker section (and therefore a larger step up to the platform of the slide when in and the concomitant loss of headroom), or will have this sort of springboard effect due to its skinny thickness. WRV could go to a thicker tube-wall section (a lot thicker) to alleviate some of the springiness, but I don't think it would ever be w/out a sort of spring board feeling.
