Reviewed a 2003 GMC SLT 4WD Extended Cab SB on Nov 6, 2009

I havent had to do many repairs, however my Transfer Case Control Module is acting up now @ 120,000 miles. I bought this truck more for the awesome SLT package it has-heated leather seats, BOSE sound system, fog lights... Its a great truck, nice power,unfortunately the body parts(heated signal mirrors) are NOT cheap.

Reviewed a 2003 GMC SLT 4WD Extended Cab SB on Jan 31, 2008

Its been an OK truck, it gets me to work during the week and gets me out hunting and fishing on the weekends. Its quick, brakes good, rides alright and looks half decent I guess. I could deffinetly use a heavier duty truck for my off-pavement adventures and towing but this one is getting me by. If I dont trade it on a deisel this year I will be lifting it on 9" and 37"s.
