I have owned a Dodge with a 6BT and loved it. The problem was the Dodge truck that was attached to the engine, but the drivetrain was fabulous. Mine was a '91 so it was the earlier body design that was almost 20 years old. Maybe the newer trucks are better.

I have driven Ford's and the truck itself is far superior minus the engine. The V8 appears that it would be MUCH more difficult to work on.

My ideal truck would be the Ford truck with the Cummins 6BT.
