It's cooling down and getting dark early, a recipe for getting little work done. :/
If Ford had a decent diesel in the 4.0L range I'd have gone that route, but the baby V-6 Powerstroke sucks as bad as the 6.0L it's based off. I could have gone Cummins 4BT, which is found in Ford medium duty trucks as factory option sometimes, but from my research the Isuzu is a better choice and even less expensive.
