Jim,
I will be installing my Blue Ox base plate on the Ranger next week.
This is the requirements from Blue Ox on hitch height to base plate height.
CAUTION: It is important that the attachment
points at the center of the attachment tabs and the
center of the coach's hitch receiver should be of
equal distance. If a deviation must occur, then it is
recommended that the hitch receiver be no more
than 3” above or below the attachment tabs of the
baseplate.
