I am looking to trade in my truck for a larger one for towing and hauling wood. I am looking at two vehicles...a chevy 2500HD crew cab with a 6.0L gas engine and a 2010 Dodge Ram 2500 with a 6.7 Cummins Diesel engine. Both will tow, both will haul, but which would you go with...the new gas engine, or the used diesel? (22,000 miles).
