The only problem we have had is with the ladder for the overhead. One of the rubber end caps had a hole in it and the metal was poking through making a gouge in the flooring. We put some duct tape on the sharp part of the ladder and bought new caps.
I haven't noticed any scuffing at all. We did buy a couple of throw rugs so that our feet would not be cold when winter camping. I don't like the feel of cold linoleum on my bare feet. :-)
