Question-did the truck have some sort of bed or box on the back originally? Or was it used as a tractor-trailer setup? An option would be to keep the logo as is on the door, then use the one from the cap on either a sign on a stake bed/box, or if it was a tractor/trailer, find an appropriat box trailer to put the logo on. Of course with permission from the company, if they are still in business.
