Can't you plumb the shocks to separate schrader valves? Being a truck camper owner, I can tell you that the trucks airbags need to be on separate lines to minimize the sway when that VERY top heavy load wants to tip to one side or the other.One thing i realized that I will need to do is make a sway bar since tne air shocks are plumbed together. I am thinking a 7/16" round bar and bend it to fit the application. What I don't know is what kind of steel and temper to get.
If someone can point me in the right direction I would appreciate it.
