I built these brackets to mount the Firestone W013585412 airbag. One side of the bracket is reinforced with webbing. A 7 inch diameter .25" round plate is used on the other side, with an aluminum spacer. The air inlet side has a 6" diameter plate. I bought the round plates off of Ebay from Sirius Steel. I had help from a Mechanical Engineer friend who modeled the brackets on Solid Works. He suggested adding the webbing to strengthen the plate, for increased safety. There's 2700 lbs static load on the brackets. The airgbags have internal bump stops so that the Moho will not drag the bumper on the ground when fully deflated.
The suspension travel is quite good. With 120 PSI it goes up until the shock absorbers are out all the way.
This airbag has been used before on motorhomes.
