Andersen Hitch issue

I do place blocks under the legs before I start. In order to get enough travel of the legs I have to have them in the upper most position with the drop legs touching the blocks. This gives me the use of the entire travel distance of the landing gear to get above the ball. The problem comes with getting the trailer level after moving the truck. If the trailer is level when I first park in the site I don't have too much trouble but if I'm nose high I don't have enough down travel to get level because I had to start with the landing gear at the highest point. I'll try letting air out of the bags to lower the truck a little if I get into that situation again, hopefully that will help. Otherwise I think I'll upgrade to the dual motor system with the larger travel distance.
