A device called a ramp-rack may be used as a rack for the body of a stake body truck in a first mode, and as a ramp in a second mode, for rolling equipment between the bed and the ground. The ramp-rack may be hinged, so when used as a ramp, it will be longer than when used as a rack. Two or more ramp racks may be stacked, when they are used as a rack on the bed of a truck.
