New Class C's don't come with cab carpeting now?

While shopping for our new larger and longer class c, we noticed that most of the major manufacturers no long carpet the cab. Didn't seem to matter if it was Chevy or Ford, they all had black rubber floor like you'd have in a commercial truck. My 2004 Winnebago had nice carpeting, and it ran from the cab to the kitchen where it's vinyl. Guess the manufacturers when they decided to use vinyl thru out the MH felt it unnecessary put carpeting in the cab since they get the cut-away chassis without it.
wonder how much it would cost to get it carpeted. It does insulate the sound and engine heat somewhat.
