If I were a frequent tower, it'd be turbo-diesel all the way. There's definately an advantage in the mileage and towing capacity there. But I don't tow often so it isn't necessary. Plus, I got a decent deal on the truck.
The guy that sold me this Dodge bought a Ford F-550 Diesel flat/dump bed that has a GCWR of something like 30,000 pounds. Perfect for him - he'll put 4 pallets of sod on the flatbed, and tow his tractor and attachments behind.
I think the Big-3 dropped the ball on trucks by not considering the 4BT for lighter duty applications...like 1/2 ton FWDs and up to 3/4 ton RWD applications.
It’s a nice small-displacement turbo-diesel engine, already in production, and tested in many bread truck and UPS applications.
