I have put over 300000 miles and never touched the inside of the motor. 5.3 i think. It gets 18 mpg. I have a 345 rear end, auto. Used both in construction work and pleasure. Has been an excellent pickup, and still looks good. Did replace transmission @ 235000.

I have had many cars and trucks foreign and domestic. By far this is the best and most reliable vehicle I have ever owned. We live on acreage and the 4x4 is like a billy goat. The only thing mechanical that has needed to be replaced are the power window motors and the gas pick-up in the gas tank. I have not even needed a brake job probably because I do little towing and it is driven more like a passenger car. I take very good care of my truck,oil and transmission fluid changes, wash and wax and I am careful when I use the 4x4. Gas mileage around town is 15-16 and on the interstate 18-19. It is more comfortable on trips than our cars. Feel very safe in all kinds of weather. Love it.

The features on my GMC SLE extended cab
(3 door) are fantastic! This is the
BEST "General" I've ever owned; and
I've had a few. This truck has modern
V8 power; modern comfort (lots of
options); modern sound system w / CD;
modern ride (suspension and disc brakes
@ all four corners) If you can find one
(99' +)with "mimimal" milage........get
it! For a 1/2 ton pick-up truck it's
got more "creature" options than a 99'
Cadillac........I continue to forget
that I have to manually turn on/off the
head lights in my other vehical! WOW!
