Even before any addons this truck got good highway mileage(17/19)at 65/70. With the addition of K&N, Superchip, and 4"turbo/back, this truck hauls AND gets great mileage (19/22) at 65/70 mph..Combined city\highway is an easy 17mpg..Pulling a 16000# 5th wheel before mods, mpg was 10/12, but now I can hardly wait to see what the mileage will be. Also a very roomy, quiet, and comfortable truck on long trips. The BOSE sound, and XM radio make long hours on the road even more enjoyable. I drive a Ford 4x4 company truck, and there is NO comparrison.
Tight handeling and manuverability. A great ride, and plenty of power.
Intigrated trailer brake controller,auto darkening trailer mirrors,electric radiator fans,better computer programers.If superchip can do it,why can't G.M.? Also, a 4' stock header back system like Dodge(ouch).
