If you are using the truck as a sales vehicle, or to tote the kids around, then yes, go with an electric fan, if you use it for it's intended perpus, then stick with the direct drive fan.

You know, I've only ever open my truck's hood during oil changes. I really should take a look at that design. I suppose the fan design goes along with most of the other engineering in the truck, which seems to be absolute overkill for commuting, but comes in handy when you're pull a trailer with a loaded bed, which is what these vehicles were meant for.
