Reviewed a 1997 GMC K1500 SLT 4WD Extended Cab SB on Aug. 07, 2008

I've got 275k+ on the original engine and tranny. I work and tow with it everyday. 4x4 is awesome braking lacking but that's to be expected from drum brakes. Gas is not the greatest but it makes up for it by being dependable. Here's the hint to making it last, oil change every 5k no exceptions!

This truck has been awesome. All except the a/c going on the frits and the leekey valve, even with the valve it has plenty of power. It is also a blast to drive, with its four wheel capibilites. This truck is a Beast.

Bought this truck new and noticed the box was crooked. Returned to the dealer and they said there was nothing they could do with it. Talked to the salesman who said there was lots like that and many with creases in the tailgate from stamping the hole for the handle. How could a reputable company let such shoddy workmanship leave the factory? JUNK

Strong running, powerful truck that has had next to no problems. Mine has 150+ thousand miles on it and I use it for work and trail driving only, basically i beat the doors off the poor beast and it runs like a new truck still.
