in my 37 i used the original type "jute" underlayment and then put the rubber mat on top. Seems to work for me.

Edit: when I did it I undercut the "jute" by about 1/2" all the way around so that the rubber would "lay over" the jute and you couldn't see it. Looks nice.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
