Bought the truck Dec. 16 2007 assembled in Texas. So far have 12000 mi, had no mechanical problems and no strange noises.the truck does bounce some on the freeway when there is nothing in the bed. There is one thing I don't like and it is at the dealers now for, and that is to have the radio replaced. There is static, scratching noise in the AM section of the radio when I hit little bumps on the road or freeway. Otherwise the JBL 440 watt 12 speaker 4 cd radio sounds very cheap.
Overall I'm happy. Great power. Haul heavy loads all the time and have had no issues with ride. Ride actually gets better as the bed is weighted. Empty bed on rough roads cause entire truck to resonate... this is common in trucks though. Inside plastic; radio and dash material is cheap (planned to get aftermarket nav as it has better features). Bluetooth is actually no good, no one can hear me clearly. JBL subwoofer under rear seat is poorly placed, should have stuck it behind the seat. Center channel on dash makes noise if covered up with paper. Rear head rests obstruct view. No memory seats, rear ac vents or step lights standard on DC Limited? I couldn't get a moonroof on the DC.
5.7 engine's power, inside seating, power folding mirrors, in/out styling, ride and performance is great with a load. 6 spd transmission shifts smoothly. Homelink. Center armrest is nice and well thought out.
MPG. Ignition s/b on dash, not steering column. Use better plastic. More/better storage. Get rid of huge blind spots. 20" rim s/b standard on Limited. AC plug in the bed. Seat heater switches are flimsy. Dampen ride when bed is empty. Need 2 fan cntls for 2 zone climate. Fuel filler lock.
Great handling except for a little bed bounce. Have about 8000 miles with no problems what so ever. Stopped burning rubber at stop lights because of gas economy but MAN the power is awesome. Get plenty of looks and compliments. Put new chrome grille and chromed out all exterior parts "It's a head turner!"
Of course the 5.7L V8..
Make many, many more without cheap paint and chrome all exterior accessories. Offer roll-up tonneau cover as standard.
After 6 months of driving this vehicle, I find that it delivers on things like towing and hauling. I guarantee you will not find another truck that has better braking ability and power.
Brakes, brakes, brakes. I can't say enough about the braking ability on this truck. Low end torque makes towing my boat (Tahoe 215CC, aboout 3000 lbs) seem like it's not even back there, and this is in the 4.7L. Handling is very good as well.
