I completely love this truck. I modified this truck and added an additional 35 hp to the existing 403, wow! Need I say more! Added side steps 5" oval, bed cover with rear spoiler and lite, complete tint. Modified exaust for deeper purr, added air intake, Customized GMC Logo cyrstalized. Black it out completely, changed door handles to black got rid of chrome strip, added OMEX 6000K halogen kit, got rid of the orange on front head light assembly, changed tailpipe all black 5" oval, sits on 26" black rims, with a lowered supension kit 2"f 5"b, looks mighty damm good! Wish I could post a picture. This is what a real truck should look like, love it, love it, love it.
Best Truck I ever owned!

I have built quite a few cars and trucks over the years, this by far out performs them in an all around sense. I got a pretty basic truck for my buisness so that's why comfort is a marked low. My only complaints are that I didn't go bigger with an extended or crew cab, and we need the 6 speed in the basic trucks too. The motor is the most impressive part of this truck. I have a tool box and tonneau, and now acheive up to 22 mpg. The six speed wouldn't work here. My friends Scion TC only get 25-27 mpg average so I'm very very happy.

2008 GMC Sierra 1500 SLE2 4dr Extended Cab 6.5 ft. SB (5.3L 8cyl 4A)

I test drove every make of truck and this one got my money. Sharp truck and a real headturner with my Black Z-71. Power is great and off road ability is only topped by a Wrangler (I'm an avid Jeeper). Can't say enough about the ride comfort and quiet demeanor, very nice interior. I was looking for a truck, not a Prius or Cadillac. This is the perfect truck.
Disappointed

I have loved Chevrolets and GMCs for 30 years. My 03 Chevy Silverado was the best truck I have ever had. The 08 GMC has been the most disappointing truck I have ever purchased. I am constantly getting alarms that include: Park assist off, air bag, low tires when they are not. On top of the alarms that the dealer cannot fix I have had two interior fans replaced and they are rattling again. The motor is tapping even though I do the recommended everything. The ABS brakes act like I am on ice on dry road. Cheaper braking system. Already have warped discs. My o3 brakes went 144K miles. The sun visors are not wide enough to block the sun. Cannot handle the same trailer as the 03.
Poor Throttle Response

This truck replaced my 2001 GMC Sierra 4wd with the 5.3 motor. The throttle response on the 4.8 motor is pathetic. The traction control is overly sensitive, and the truck jumps out of passing gear too soon. The truck is comfortable, quiet, and handles well. The brakes are a major improvement over my previous 2001 Sierra. I love the lighter weight of the tail-gate.
