I'm trying to figure out what it'll cost to drive the new/old '57 GMC dump truck I got home next time I come to Reno. It's a 1957 GMC 350 dump truck with a 270 six,SM420 4 speed,and 2 speed axle,and 22.5 wheels.
Can anybody with a similar set up give me some idea what mileage it might get? I don't run more than 60 mph,and don't plan any stops other than gas and coffee.
Thanks for any info you choose to share!
