the truck bed about 2"- 6" in front of the rear axle
for proper weight distribution (Figure 1).

tween your trailer and the cab corner of the truck when
making sharp turns.
2. Locate and mark the are for the center of the hitch
ball.

lines, etc. before making cut-out or drilling any holes.
It may be necessary to move the assembly, but you

following two methods on the next pages or the
purchase of a C-52 kit.
