The Flip Up option allows the Mighty Hauler to fold up for easy storage on the back of your truck or camper. The flip up model locks in both the up and down position keeping your motorcycle safe. Once folded up the carrier can remain on the back of your truck or camper out of the way. The pivot point is made using a ¼” wall tube and a ¾” rod. Each point on the tube is fully gusseted to the mast.
