molded rubber instead of carpet

Buddy of mine went to a auto trade school and one of the trucks they built they striped all the interior out re routed any wiring and cleaned up the floor so nothing was in the way and sprayed the whole floor with rhino liner/linex or what ever you want to call it. He said you could go mudding all day with the doors/top off and at the end of the day just hose out the interior and it was squeaky clean. If I ever build a toy truck this is the route I will go.
