i miss my 03 gmc 4x4 like mad, that truck had the balls to rip a house down, but 9 to 10 mpg made me sell it. i had 4.10 gears, and the 6.0 engine. in the winter i snow plowed with a 8 foot fisher plow, you want to talk about being able to make a left turn and having everyone wait for you to go, no one wants to eat the blade of a plow lol
i put 33's on it, 2 1/2 inch blocks in the rear, and the indexed torsion bar keys on the front, with the tires and the cheap lift i got it 3 inches higher than stock. but i would never use the lift keys up front again, it ruined the ride, way to stiff up front.
