John or anyone

Instead of having 2 separate pumps (as John shows), couldn't one make both systems work off 1 pump & maybe a bigger tank? It would mean less amp draw on tractor system. I assume there would have to be check valves in the system so that air bag pressures weren't influenced by the on-off action of air clutches. Doesn't seem like it would be any more difficult than truck air system to operate.

I asked the TruCount folks, but they weren't too excited in getting involved w/airbag operation.
