diameter holes through the truck bed as shown in Figure 11a. Due to the fuel tank, not all holes can be drilled from
under the vehicle, but should be done later from inside the bed.

diameter holes through the truck bed as shown in Figure 11b. Due to the fuel tank, not all holes can be drilled from g g
under the vehicle, but should be done later from inside the bed.

11. Align the holes on the template (provided with the gooseneck hitch) with the holes previously drilled through the
bed. Be sure that the template is properly oriented toward the front of the vehicle (see Figure 12). Center punch the
holes that will be used to cut the opening in the bed. If the vehicle is equipped with a bed liner, a section of the bed
liner must be cut away so that the gooseneck platform can contact the bed corrugations.
