When you are in auto level position, all jacks are down, what is your steps to get trailer on the hitch? Specifically, what do you do to get the back 4 jacks up?
On my Ground Control 3.0, 4 jacks, 2 front, 2 rear, DO NOT have the truck bed under the pinbox, push retract all, it raises the rear jacks, and front, then push hitch height, and the front goes up to where you unhitched from.
Hitch height only works if your front was higher than the rear when you unhitched.
