The mats in our Roadtrek 1996 and present 2008 were custom made for or by Roadtrek. I recently decided that the driver side needed to be replaced and couldn't come up with a carpet replacement. So both driver and passenger foot well mats were replaced by rubber ones. Not quite as nice looking, but more serviceable and easier to clean.
If I have a concern, it will be the movement of the driver side mat up underneath the pedals. The rubber mats do have spikes on the underside, so maybe they won't move.
Cannot remember having a centre floor mat in front of the doghouse. We buy a mat to fit the area between the two front seats, another to fit in the entrance doorway, another to fit at the rear of the dropped floor and a runner to cover the dropped floor. The fun part is trying to colour co-ordinate them.
