I have it installed
In my coach. Sure is a nice system. Having a functional air level system is something I really appreciate.
I have installed one other of Keith’s system in a 73 just last november.
It is not terribly difficult to install, but does take a little doing. Different coaches can have a few different issues to overcome.
It is also still available. Keith should chime in.

Mark,
I know for a fact that it is still available. I would have bought the set when I first saw it, but Keith didn't have the valves yet and since our Chaumière is a 73-23, I didn't have the valves to reuse. As your coach is also a 73, you will need to buy Keith'e valve set too.
I have a working system, but if I had not poured a bunch of effort into making it work just before Keith made this work, I would have the Micro-level. It is still an open option to me.

from my recent experience, I would advice of a few things.
1. buy Keith's valves. they are new, and they are larger. I had ran my stock valves for a while, but they kept randomly giving up. Not sure if related to how the microlevel triggers them, or just 45 year old valves. His valves are larger and raise and drop much faster. I was replacing an electro-level 1 system. for a 73, you will need the valves. It does take a little bit of fabrication to mount and wire up his valves.
2. I also would make sure you have a nice new viair compressor. The stock one works, but it is slow.
3. I also recommend some air tank. does not need to be large one, but if you don't have an air tank, the compressor can short cycle too easily.
this is based on my 75 I have running microlevel system. I have a viair compressor, the stock larger air tank. I have installed new airlines. I am running sully style air bags. The system works great, and is very quick to go up and down.
I installed a system on a 73. we had a little struggle running the harness, as this 73(not sure all are the same), had some hard sealant from the fenders sealing to frame, so I had to drill a hole carefully to route the harness between the frame and the body, alongside the airlines and brake line. I had to disassemble the passengerside harness connector in order to fish it through the hole. On my 75, I had just enough space between frame and body, to fit the connector through.
the 73 we kept a stock (it was actually NOS dana) pump, and there is No air tank. the compressor kinda kicks in and out too often. there is no buffer of air volume at pressure. this was just installed last October, so I am going to add an airtank to that coach before we go too much further with it. Also need to make sure it is leak free, I think there might be a fitting leaking somewhere. the stock pump works, but it is slow when compared to viair in my coach.

Yep, Microlevel is still available!
Valves have been hard to come by lately, supplier issues due to covid I hear. There's nothing magic about them, you just need 4 2 way valves of any size. I usually buy 3/8" valves. You are more than welcome to supply your own valves.
I buy them from ThorBros, good valves at good prices.

Microlevel does assume you have a good Air Compressor and needs 1 good air line to each air bag. A lot of coaches have really brittle, leaky lines so it's worth replacing them. 50 feet of DOT air line is pretty cheap.
The Microlevel installs in the stock hole for Power level or Electrol level, the valve block needs to be mounted somewhere, mine is mounted to the radiator support. I don't supply a bracket as every install is different.
