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

Yes,

We love it! One of the first things that we always was to rip out the carpeting, and replace it with rubber mats. The carpet always got dirty, and it was hot, and didn't provide much sound damping.

It looks like the manufacturers finally listened and put in the rubber mat. Now we just cut carpet remnants to fit, lay them over the rubber mat, and when they get stained and dirty, toss 'em out.
