I use the air suspension to hook and un hook,It takes the load off the landing gear so I never have to raise and lower the gear,pull the pins and drop the pads to the ground or close as possible ,dump the air and drive out -mark the spot before you level and return to that mark and reverse the procedure to hook up - quicker .
however beware the truck moves very slightly back and forth as the suspension goes up and down,as least mine does.
