I replaced the carpet in our previous pc (2010 2350). The vinyl flooring does cover the entire floor. The carpet was attached by a LOT of staples along the edges, and you'll need to remove them. There were no tack strips anywhere in the 2350. There was no finished edge at the step down to the cab area. Removing the carpet was fairly simple. I installed laminate flooring over the vinyl flooring, and that wasn't complicated if you've ever installed laminate.
I wonder if, when the slide comes in and out, the laminate would scratch.Judi
