Converting to Air Levellers from Hydraulic

I want to have air levelling on my next coach for several reasons:
1. Lots of Florida parks have soft sand bases that compress if you are there for a long time....air levelling gives you a larger footprint and therefore lower compaction pressure.....and thus less chance of buried feet when it's time to move.
2. My DW has a bad habit of reaching in at the last moment to reposition the foot boards on levelling, so that using a spreading board leads to unnecessary stress for the person on the levelller controls.
3. Hydraulic levellers seem to be more apt to torque the frame of the coach and break the windshield.

Many models of coach, even those with airbag suspension only come with hydraulic levellers. In order to be able to look at them I am wondering how big a deal it is to convert a hydraulic leveller coach to an air-levelling coach? Does anyone know?

    "the size of the air cylinders would have to be approx 5 times larger in diameter." They are call air bags and you already have them on your coach.

    Three new ride height/air leveling valves... $600... four as you have a tag axle $800. Touch pad $500. Computer control board $600. 12V air compressor $300. Installing the three extra air lines and control wires $800. Finding the wiring harness... impossible.
  • Probably not practical. If the hydraulic system operates at 2000 psi lets say and the air system at100 psi, the size of the air cylinders would have to be approx 5 times larger in diameter.
