I have the info regarding setting ride height by distance
between ground and the frame holes.
Would it be too much to ask if somebody has already found
(and recorded) an exterior measurement for correct setting?
How about a distance between ground and center of the small
mini-skirt between the rear wheels? Easily determined with
nothing more elaborate than a common yardstick and doesn't
require crawling under the coach? At age of 73, my body's
flexibility has just about totally disappeared and just the
job of getting back on my feet from a position on the ground
has become a pretty big chore. (;<p)

OOOPS!
Meant to specify the distance from ground to the
JOINT/SEAM between the top of the rear wheel well
and the small middle skirt.

Do it by the book. We found that a 1/4 inch difference will make a 150 to 200 pound difference on the load carried by that tire.
Once they are set exactly, then cut yourself some 2x2 or 2x4 measuring blocks and stick them under the frame.
Measuring to the wheel cutout is very inaccurate. No two coaches are the same due to the thickness of the pads (2 different ones were used), how badly squished your pads are, and how many pads you have missing.
I have the sizes for the blocks stored somewhere. I just got home from Bean Station. If I can find the numbers I'll post them later tonight. Also you could search the forum as I posted these more than one over the last couple of years.

Mac,
You need to get some kid to lay down under there with a tape measure once
the ride height is set to spec and make sure it is exact. Now you can take
any point of the rear of the GMC and use it as a reference. I have used the
center of a talilight screw, the center of the bogey greaser etc. Any rear
point will work as a quick reference.

Using a straight edge, line up the center of the hub cap/wheel with the zerks on the bogie pins (some prefer to run just a tad lower than that). This eliminates all the variables of tire pressure, tire size, body pads, metric dimensions (vbg), etc.

But that's too easy and makes too much sense. Surely there's a superior and
more complicated way. (That's Alex Sirum's method, too.)

Definitely WAY TOO EASY, and right there where you make the adjustment too......
I cut spacer blocks to put between the street and the frame right below the
slots, but....it goes like this.....make an adjustment, lay on the ground and
check, then repeat that process about 10 times for each side......dang I like
this new concept !

Bill Hubler has the right idea on ride height. In the compartment on the
Pass side of the coach behind the refrigerator he keeps a 1/2" dia wooden
dowel with a piece of electrical tape wrapped around it at the height of the
fenderwell opening. Also inside the compartment is a 12v DC air compressor
with a hose long enough to reach the drivers side of the coach. (He has a
23' Birch.His air bags are fitted with shrader valves only. He merely holds
up the stick, attatches the hose to the shrader valve and starts the
compressor. Pops it off the fitting when the tape matches the wheel opening.

Your method works well. I just beveled opposite ends of the stick so I could
drive off and roll them out easily in the event I lowered too much. Of
course, I make the adjustments with the Schrader valves at the wheels. Using
the John/Gary approach it's even easier with a remote control.
Now about those who are challenged by technology (the name "Dan Gregg" comes
to mind), learn how to use the equipment before you become road kill on the
infobahn. Email addresses are easy to steal.

Bob,
When one does what you note below the uprights to which the air bags are
attached are 90 degrees perpendicular to the ground.
If you've got a good eye you can see it.
