A fork lift for a truck may have at least one mounting beam for pivotally supporting a fork lift mast on a truck frame. The mounting beam may be mounted in a bed of the truck via other structural members and bolts that extend through the members, bed, and truck frame. The fork lift may extend well below a level of the truck bed to enable engagement of palletized loads resting on the ground by the forks of the fork lift. The fork lift may have hydraulics including pumps, solenoids and motors that may be supported in a tool box that also helps to secure the mounting beam. An electric over hydraulic control system enables remote control from within the cab of the truck. Fork position during stabbing of a pallet may be viewed on a monitor in the cab, with the monitor operatively connected to one or more cameras.
