Picked up my duramax a while back and it didn't have the bottle jack with it. I went to a local junkyard and asked the guy what size jack came with the truck and he got all mad at me and tryed to make me feel stupid for wanting to "trust my life" with a bottle jack, so I just bought a 12 ton. I fits underneath the rear axle but it seems a little tall for the front. Anybody know what size jack their trucks came with? I have an 02 with 265/75R16
