I am considering buying a crew cab diesel to tow a toy hauler. The Chevy 6.6, Dodge 5.9 and Ford 6.0 all have good/bad points. The Chevys from what I have read have the best transmission (Allison)& best mileage (acording to MotorTrend). Negatives are lowest tow rating (w/3.73 gear) and somewhat dated look. Dodge is the loudest at idle, has a harsh ride, tightest back seat and only a four speed trans w/questionable reliability. It has the best maneuverability, towing rating and lower pricing. The Ford seems to have the best ride (will even be better with the new front suspension), towing acceleration and roomiest cab. Its the least maneuverable (at least until the new suspension) and gets the worst mileage (a full 2 mpg less unloaded at highway speed than Chevy, .7 less than Dodge according to MotorTrend). The mileage is a big concern for me since 90% of my driving will not involve towing. Any input will be appreciated, especially about the milage.
