Central ND | We have a 72 with 1693 and 501k original miles. 79 has a 3406 and factory walk in flattop 60" sleeper on 8 bag air ride, it had a 15 speed with od against the dash but I switched it to a 13 speed a few years ago. The leg room is definitely a concern on those older trucks, if we drove our 79 more id be tempted to do a pete big home conversion | |
