Ok I have had this truck for a week and I love it. I traded in my 07 1500 LS Crew Cab with a 4.8L because it didn't tow my trailer as good as I wanted. After dirving this truck for a week it flat out performs my 07, in every aspect. You can feel the power difference in the 08. Gas mileage has been good for me as well. I averaged 18.3 on the highway last night going 75-80 for 300 miles round trip. I guess with some mods it should get better. Not a fan of the smaller looking tires on this truck. As big as this truck is you would expect tires that fill the wheel wells. Again this is an excellent truck all around Great job GM.
Power! Interior is not too shabby, have a little better than a 2LT but not as much as an LTZ
Tire size this truck demands bigger tires. Seats hurt my back but I guess I just need to adjust them to me (same as the 07 1500 was). OnStar offers hands free phone for a fee. Why can't I program my phone thru the truck and use the onboard system hands free.
