The Stovebolt Site Forums The Parking Lot Tons 'o Fun What exactly do I have?

Well a 1-ton GMC is a 250. A 280 is a 1-1/4 ton. A 300 is a 1-1/2 ton. A 350 is a 2-ton.

GMC models continue with 400, 450 and so on to 900 series trucks. After the 250 models all of them have duals on the rear far as I know.
