Yea, that is why that large one on the truck roof looks dangerous to me. In the olden days truck roof's were stronger, I guess. Today, that much water would most likely damage the truck.
They used to put it up there so gravity would transfer the water to the camper without a pump. Using a pump, the truck bed or tailgate would work just fine.
