When I went to Arctic Man a few weeks ago I rode with a friend of mine. He's got a 07 Dodge Ram 3500 with the Cummins diesel motor in it.
He pulled a 28 foot travel trailer that weighed 7K+, had 2 long track Ski Doo Summits on the sled bed mounted on the bed of his truck with my Honda generator, a half dozen 5 gallon fuel cans (full). All up, I'd guess he was pulling close to 9k lbs and he was getting somewhere around 15-16 mpg.
I could not believe how good that thing was on fuel towing all that weight. He had no problem passing slower traffic either and I couldn't even tell he was towing anything. I've another friend with basically the same truck (04) and he gets 15-17 mpg pulling his enclosed trailer fully loaded with 4 sleds and fuel. He told me he gets 20-24 mpg empty.
I've always told myself I don't need a diesel but with that kind of mileage and power, I am considering buying a Ram 2500 in the not too distant future.
