There's a sound deadener kit similar to OEM pads that were used under stock rubber mats. It consists of a white closed-cell foam pad and heavy black tarpaper-like pad. Seems as good as the original stuff.
IIRC, I have bought three reproduction rubber mats in the last several years. They looked and fit great when new, but began to rot and fall apart after just a few years.
One of them didn't even make it into the truck -- it rotted in storage before I went to install it.
I have never considered carpet and have thought about trying a full-length vinyl mat next time. They seem to hold up much better than the crappy rubber mats that are being sold now.
