I don't think you'll see any significant difference between these trucks for gas mileage. May as well pick the one you like best :D

I'm a Chevy man myself, but heard good about both.

Still waiting for a GM to put a Duramax in a Suburban! Of course, also waiting for bio-diesel to get popular and only cost $1.50/gal. :D

I just hope my Duramax doesn't need a new shortblock at 15,000 miles like the FORD did. They also put a rebuilt shortblock in after the took the cab off the frame. The easiest way to work on these. The warranty states they have the right to use rebuilt parts.

My 06 cummins got around 15 in town and Hwy 10 when I was pulling my X45 long distance. When I hit around 30k on the mileage it starting getting better and now gets around 17-18 on the hwy empty still about 15 in town and about 11-12 when towing heavy.

02 DURAMAX 2500 HD CREW CAB. I have banks exhaust, hypertech programmer, air raid intake. I think they have the bugs out now. Gm replaced all my injectors at 98,000 and the a clip in the torque converter put a pin hole in the case. It coated the boat and trailer with a fine mist for 200mi. The truck runs very strong with the few mods I have done and it trailers like a dream. Never a worry about merging in traffic or steep grades.
