GM guy i drive enough miles that i will wear them out before they age out.. I just got home from a 850 mile trip and the sub ran perfect the first tank went 659 miles well not empty just found cheap fuel 33.8 gallons just shy of 20 mpg's running 70-75 mph. just about 3 times the mileage of 454 dually a whoping 7 mpg but it was towing 5500 pounds on the trailer so it was right about 15,000 lbs not to bad for a gasser.. lucky it was one way trip for the dually i know the sub could of pulled it but its hard to get the gooseneck through the back doors..
dolly! put a gooseneck ball in a pickup box trailer, then hook the goose to the trailer then to the burb! 88-98 pickup white in color for the donor to make it match!
