So, my thinking is the slots were used in production, but are not the greatest idea in the real world now.
The rear slots are several feet behind the bogie, which is the suspension point of the rear wheels. Unless you are checking the ride height on a
perfectly flat level piece of concrete, you could have severe errors in your measurement. Not to mention you can't access the slot under the
generator anyway.
I measure from the ground to the bogie Zerks. This is the pivot point for the rear suspension and mid-way between the two rear wheels. At this point
the rear measurement is not affected by the front height or need to be level surface front to back. Also the area between the two wheels is most
likely to be reasonably flat if not on a concrete surface.
I believe the measurement is 13.25" on my coach to the Zerks.
I know some measure to the top of the rear wheel-wells. I believe this measurement can introduce some errors and uncertanties as well. That
measurement is on the body, not to the frame. The body is sitting on rubber pads and the weights and distributions can change significantly with
fresh and black water quantities and also propane load introducing some amounts of errors.
What say yeh?
Just my farm-boy mechanic way of seeing things.

My Staff says I never listen to them, or something like that
