What? You haven't bought one yet? I love this truck and you will too. Powerful beyond my expectations and hauls my 19' ski boat up and down hills at whatever speed I am comfortable without any dramatic shifting, engine or transmission noise and without any noticeable difference in gas mileage.
Long highway trips loaded with kids, dogs and camping gear is a dream. Everything about this truck reflects thoughtful engineering and manufacturing.
If you have had a bad experience with any other truck, you need to buy one of these. You won't ever want to get rid of it.
My dealership experience has been very positive, and they even let me take the trip on an overnight coast trip to help me decide whether to purchase or not.
If you buy used, insist on a GM extended warranty (they won't offer it unless you ask) instead of their after market warranty which is less comprehensive and more expensive. They get a bigger kickback, so they offer this one first.
I have no complaints, but would recommend you buy the rig with tow/haul transmission if you intend to haul something heavy. It is bullet-proof and makes hauling things a breeze.
Also, spend the extra money and get step side rails (Smitty Bilt or similar) which makes getting in and out more comfortable for shorter folks.
Unless you've done an engine swap in your truck, there is no way it could have a 5.7 (350 C.I.) in it. It would be either a 4.8 or a 5.3 V8 in a 1/2 ton p/u.
The 5.7l V8's were available up through model year 2000. My dad has a 2000 model GMC Sierra 1500 with the 5.7l V8 in it.
That truck can pull damned near anything.
