How does the Companion install?
One of the reasons the Companion is so innovative is because the mounting system is beneath the bed of the truck, mounted to the frame. This mounting system includes a four-inch hole in the bed. The Companion base has a square post that fits into this hole.
After the Companion base is set into the mounting hole, a lever in the wheelwell is turned, engaging a pin through the post. A draw-down bolt on top of the post creates upward pressure on the pin. A locking bracket holds the bolt in place.
The last step is locking the coupler portion of the hitch on top of the base.
