I do .....
2005, 2500, 4WD, 8.1 Vortec, 4L80E, 4.10:1 locking rear
I love it .... The rest of my fleet includes a Suburban 2500 4X4, 454SS pickup & an E350 Van so its uniqueness crosses over all 3
And I know some one is going to ask so ..... gas mileage, Summer [to Rhode Island or South Carolina] 16 mpg around town 10.
Fall/Winter [up to hunting camp] 12 - 13 mpg. Speed makes a HUGE difference .... this truck punches a BIG HOLE in the air ..... the difference between 55 & 75 is about 20%
