Volks,
The PO of my 89 Westy apparently spilled more than he ate when using the kitchen/tables.  Consequently, the carpeting next to the refrig/sink/stove was stained and a tad unsightly.  When trying to decide between new carpeting and any other alternative, I considered my own sloppiness and the usual state of my 8 yr. old's shoes when she comes in from the outside.  I quickly decided that a new carpet would probably soon be as nasty as the current one so I went looking for an alternative.  I finally settled on the cheapest, rectangle, clear plastic desk/chair mat that I could find at our office supply store.  It was 46" X 64".  As the interior of the Westy is 46" X 50" I only needed to cut a small portion off one end.  I easily did this with aviation snips.  I tucked the cut edge under the leading edge of the fold down rear seat and pushed the rest tight against the refrig and the wall behind the front seats.  Now I have a scuff proof, heavy duty, wall-to-wall, plastic floormat that wipes clean and is equally functional as it is pleasing to the eye.  It took me about an hour to cut to size and the mat was $40.  It will probably serve the life of the vehicle.
