I think I have my air shock absorber mounting solution!
By extending the nose of the hitch backwards, the requirement fer the shock to be on the outer most part of the arc is transferred to the rear instead of to the nose of the hitch. This will allow the shock to compress/expand in a close to vertical arrangement similar to a car/truck shock setup. This will also allow fer less interference potential fer the shock setup.
I can adjust the amount of pre-load on the hitch by inflating the air shock to compensate fer the load in the trailer. Of course, that will entail a few trial and errors on my part unless a mechanical engineer wants to chime in on the formula...
As the nose of the hitch drops (rear rises), the shock will compress. As the nose of the hitch rises (rear drops), the shock will expand. The air shock should dampen the compression of the shock and the oscillations that are being transmitted into the truck.
Standard shock tabs will attach it to the vertical and horizontal parts to allow fer attachment and pivoting of the shock absorber. When the air shock is not under any pressure, it should be fairly easy to connect/disconnect the shock or hitch.
