Work Truck
The perfect work truck needs a reliable diesel engine and a custom flatbed with dump capability. We would choose an '03 Ford Super Duty as our foundation since it is a stout platform, ran for many years, and plenty of replacement parts exist. It also came with the durable, intercooled 7.3L Power Stroke. We would also opt for the proven 4R100 automatic transmission, which is reliable behind an unmodified 7.3L engine and easier to drive for other employees.
In this case, performance engine modifications are not critical, so we would focus more on the truck's suspension and it's functionality from the cab back. An air spring suspension would help control heavy loads, and a custom aluminum flatbed with dump capability would make difficult tasks much easier.
