Reviewed a 2002 GMC SLT 4WD Extended Cab SB on May 17, 2010

i have the 5.3 v8 and have yet to hook on to a load it can't pull. 16 foot stock trailer with 4 horses and it acts like nothing is back there. It has good take off power that not many big truck have. Mpg wise with a lead foot around 16 - 18 mixture of highway and city. I put 300+ miles a week on it and it still runs as good as the day i bought it.
