any problem with 2005 Aliner Expedition before I buy?

I have an 06 LXE with aluminum skin. It's about 200lbs lighter than the fiberglass model, but does indeed show dings and dents. I made the mistake to park mine under a huge hickory nut tree one day and have a few dings to show for it. In 2005 Aliner went to a composite floor material called Performax which is far superior to their old flooring which would come apart when wet.
Here's a link to the flooring manufacturer describing their excellent product: http://www.huberwood.com/other-products/performmax
