GM,
Thanks for the info. I had thought my suburban "mat" was dried-out rubber. A more careful look at pieces I removed does seem to confirm that it is linoleum. The source for a replacement that I contacted was for a rubber mat.
The pieces of mat I have from my truck do not have a burlap backing. It is backed with something that looks like roofing tarpaper (which might explain the tarlike mastic used to adhere the mat to the plywood floor.
Here is another source of (burlap backed) linoleum in several colors. I will call him tonight and post what I find out.
Thanks, Tim
