Had some spare time yesterday and decided to change the old type tank drains and run 1/4" tubing with 1/4 turn ball valves to a location that is accessible, this was recommended to me by senor gurus and it makes sense and wonder why Newell didn't think of this. Before doing all this I put the coach in raise then put the 20 ton jack stands underneath the rear and front then hit the dump so I'm assured the coach will not squash me like a bug but I still get nervous when I was dumping the air from the tanks laying on my back watching for any movement. I've lost enough weight that it makes it much easier to get between the drive and tag wheels and scoot myself to the desired spot not as quickly as Richard but I can get there. The hardest tanks are the front tanks most certainly the one dead center of the coach, another what was Newell thinking. One thing I noticed is I had no more than a couple table spoons of water in all my tanks combined and think this is because my Junair compressor has a automatic water dump on the output air side and we replaced the air dryer soon after we bought it. Pictures will follow as I'm waiting for the sun to come up and finish the job.
When I first got our coach, I did the same. And you are right, only a few of the tanks had any indication that they had water in them.
I did have a hard time on removing a few of the drain valves, but I got a new tool to help. They are the 3 point contact vise grip pliers (they come in 3 sizes!) that allowed me to grip the brass fittings after they seemed to want to round out and grip unbelievably well.
I ganged the ball valves in 2 locations. One on the AC condenser at the front passenger side behind the headlight, and one in the engine battery bay. I did not route the ping tank in the passenger wheel well as I added a ball valve directly to the tank in that location. I exhausted each valve down and away from where I would have my head during release and held hoses in place with the standard use of tie wraps making sure to follow manufacturing guidelines.
The only thing that I need to watch is on the front ganged area, if parked in a sloped area, the front end can drop low enough where you might not be able to get your arm in the location after you have let all the air out. You probably dont need to ask me how I know.......

Likely you are missing the "frame" tanks. Although I am not certain, and Richard can confirm, but I think the crossmembers are the "tanks" for the suspension.
My recollection is that the crossmembers are about 4" x 6" rectangular tube with a drain valve on it.
Here are pictures of the one frame tank I can find and the big round one behind it and of course the small round tank in the wheel well area I didn't take a picture. I'll go back and look for the rest of them. My valve set up is NOT as pretty as yours, you did a first class job.
Follow the big air lines from the aif bags. They terminate into the frame tanks. Follow the 1/4 line from the tag air bag. It will appear that both tags go into the same frame tank but that is deceptive. The tag fram tag has a divider welded in the middle.
