I guess I cheaped out and just have the two fill fittings mounted in the left rear wheel well. Been that way for 10 years now on my 96 F350 so I guess I can live with it. I did not tee the two lines together so I could seperately adjust the air..used to have a large slide in camper that was much heavier on the left side due to all the appliances so it took more air on the left to level the truck both front to back
and left to right
