Great report with good clear photos, Jerry! I checked around that area when I did the rebuild on my throttle valve. Everything looked tight, which was a relief. I would not look forward to doing a R&R on the brake treadle valve. What a tangle of air lines and fittings! But replacing the 60 psi switches doesn't look too bad.
I am still looking for a pesky air leak that drains my wet tank from 120 to zero overnight. I have replaced both the check valves on the wet tank, with no improvement. I will take your clue and check those fittings on top of the ride height valves. If that doesn't help, my next step will be to install a 1/4 turn ball valve on each line coming out of the wet tank. Then, from a "aired-up" condition, I can close all the valves, sealing off the tank. Assuming the tank itself does not have a pin-hole leak (not impossible), then I will open the valves one at a time until I find the offending line. Then find the leak in that line.
Isn't chasing air leaks FUN! Who needs a hobby, when you have a air-suspended coach?
P.S. I got me one of them "headlight" caps at Walmart. Also works great for walking the dog in unfamiliar RV parks at night!
