Even if pickup trucks aren't, vans and service trucks are (box trucks, etc.), which are essentially built on the same engine as a pickup truck. (big pickup trucks are sold with the ability to put a custom box on on them, too)
Replace 'truck' with 'white van'.
I'm not too sure how directly replaceable those two car types are, since performance matters a hell of a lot more in a truck than in a "white van".
