After having the Blazer as a daily driver for 8 years I got a new truck today. 05 GMC crew cab dually 4x4 SLT . I am so excited. Can't believe I actually have something with AC. For the tech it has 3:73 gears which is standard on all the 3500's. I thought 4:11 was offered but they aren't. See you guys later. Maybe now I can go to some trailer further away.
