I love this truck. I got it age 15 for a first truck. The trans (4L80E) went at 142,993 miles, when it lost reverse. Very comfortable truck, I do notice when I go over bumps, the bed seems to move seperate from the cab. The interior design is pretty good, though the middle seat does not fold down for an arm rest, and the rear seats are locking, which can be a pain.
This is the best vehicle I've ever owned. My first Chevy truck since '64 . My wife has a Toyota Sequoia, and I wouldn't trade my truck for two of hers. Great power, fantastic brakes, outstanding visibility. Best back seat of any make in 2000. Actually is tilted like a regular seat. 148,000 miles, been in the shop twice for minor concerns, doesnt use any oil, and still on original brakes. Average 13-14 mpg (16 hwy), which isn't bad for 300 HP and 365 FPS of torque. Pull a 4 horse goose neck, no problem, although it does better with 3 horses. My only mistake was only buying one. Should have bought two and put one up on blocks in storage!
Gas milage is bad no matter what we have tried to do. Computer chip, air intake, dual exhaust, doesnt make a difference. Still only get 13 miles a gal. 8 miles a gal towing. Should have bought the 454 it gets same mileage and has more power.
I purchased this truck with only 17,132 miles on it it now sits a little over 38k miles. Had one minor thing a 02 sensor went out. I have used this truck for a truck and hauled a couple loads of 38k lbs. Plenty of power! Blew up my drive shaft Pulling it once too. All love the truck love it even more with the new Bully dog triple dog GT! 15 MPG running empty..
