Yes I have read your thread many times. I do plan to add a drip edge. I have not cut the darco yet because I am pretty sure it is all that is holding the floor together at this point. Mine looks much worse than your from the top side, based on that and the fact that I have this issue on both ends, replacing the entire floor seems the way to go. I had not considered the friction issue, thank you for bringing that up. I will certainly add the beveled edge on the flooring. My slide is the lippert rack and pinion flush floor side, there is a rounded piece of hard white plastic in the camper the entire length of the slide that the slide floor slides across as the slide is retracted. FRP is sounding more and more like the best fit for me.
I have also seen the videos of the group holding the slide walls up by screwing jack posts into the holes where the corner trim is removed. My slide is 12' long. I will be removing the lower two pieces of siding just as you did, exposing the studs. My plan is to screw a 16' long 2x10 to the wall studs and support this 2x10 at each end to hold up the slide as I remove the floor and put the new in. This should support the entire wall as opposed to just supporting it at the ends as they do in the youtube video. I may also have a few pieces of sill plate to remove and am worried that only supporting the walls at the corners will not be adequate once I start cutting on the sill plate.
