duramax would be cool but its like a 6k option. im gonna stick to the gas. maybe downgrade from the HD 6.0 to the 5.3L and go from 4.11 gears to 3.73 even to go easy on gas
damn them duramaxs have some power. i have it chipped. its got every option Bose speakers,leather.etc best truck i ever owned. but it is an expensive option. i need it though for the work i do
