My 67 C-10 has the original rubber floor mat, still soft and pliable. Has foam and tar board and is super quiet. Truck is a 250 3ott that purrs like a kitten which helps greatly.
My 70 K5 has carpet that's glued down to the OE front and rear rubber mats (thanks previous dummy)
I managed to get nice used front and back originals from the board with the intent to dump the carpet.
I'm sure the original mats contain more natural rubber than the repros that fall apart in a few years
I'll say it again "carpet is for cars!!!"
But hey I can be a little bias
