I'll admit Emery makes a good point(as usual :-). If the goal is to make the
front take up all the side-to-side weight difference, why not just drop the rear
a little, put both air valves on "fill" and then gradually pressurize the air
tank until the back is close to the right height. Adjust by adding or
subtracting pressure from the tank, leaving the valves in the fill position. In
this way both sides will contain exactly the same pressure and therefore have
nearly the same load. Adjust the front suspension to the correct height on each
side and you're done. No jack or beam required.
If the objective is to take up all the side-to-side unbalance in the rear (oops,
getting into the "way, way too much time on their hands" mode :-), then put a
floor jack under the center of the front and remove the front wheels. Lower the
front to about the right height and allow the rear to automatically level
itself. Measure each rear side exactly. Put the valves in the "hold" position.
Now put the front wheels back on, lower it down and adjust each side of the
front to bring the coach back to the measured height at the rear and the correct
ride height at the front. Every time the fronts are adjusted the coach will
have to be rolled back and forth to let it settle. Yup, way too much time.

I am beginning to think that some GMCers have way, way too much time on their
hands! :)
