Actually is a GMC... More details to come, but until then I was hoping to get some rough ideas from the experts out there. I am going to help my Dad sell his truck. I have one photo of it right now but will have more eventually.. As you may have noticed this 1 ton dually actually has a full width bed on it.. Which is a custom feature. GMC or Chevy never offered that as an option on this model. Everything else is completely stock, original matching numbers on engine and trans/axles etc..
