I paid a very old man $400 for this truck and intend to drive it daily. It is/was a basket case and I wish to return it to glory. I have no intention of extensive paint and body, I dig its' original patina quite a bit and wish to maintain its' appearance as rather "period correct" while building it to be tougher than the law allows - a sleeper of sorts! Unfortunately the RPO sticker has been removed from the truck and I need/want to decipher the options in an effort to recreate something accurate. The VIN plate in the door has a line that reads : camper loading C G data CWR 2012 DIM A. 77IN DIM B. 22IN What does that mean OR -more importantly- what specific RPO codes are represented there?
