Just bought this truck today to use for pulling my big tandem dually gooseneck trailers. I haul 4 cords of wood on each trailer, so, I am pulling a pretty heavy load. It is a 1992, GMC Kodiak, 3116 cat, 10 speed Fuller trans, air brakes, air ride, and of course, a SLEEPER box. Truck has 381,000 miles on it. Oh, the trailer was not part of the deal. I got it for $5600.00. Drove it about 70 miles to get it home, and it ran great. A/C will freeze you out of the cab. This is quite a step up from my current 02 Dodge 3500, Cummins, flatbed.
