Based in Albuquerque, New Mexico, R.D. Trucking was Martin "Rubber Duck" Penwald's owner/operator trucking business. This is a variation on the original artwork as seen on Rubber Duck's black Mack RS-712LST in the legendary 1978 film, Convoy. This version of the R.D. Trucking Custom shirt features a nice vintage look with subtle fading, cracking and chips to make it look like it's been waded up in the back of a sleeper cab since the 70s.
