'07 Chevy 2500HD with a 6.0. She's got about 55,000 miles on her now. Had 43k when I bought her in February. I put on the window vents, bug guard, nerf bars, fender flares, mud flaps, and exhaust. This winter she's getting straight pipes (Magnaflow isn't loud enough
) and a set of 285/75/16 Cooper STT tires.
