Ride Height & Air Regulators Identification?

While winterizing our coach I was crawling around under the front looking at the generator and looked up to the area inside of the driver's side front wheel and saw this apparatus.  Any idea as to what it is?  Thanks in advance.

George, that is the front ride height valve. There is one in the front center & 2 in the rear.

Thanks Barry! 

In the same general area (between the front wheels), between two tanks (which I assume are air tanks), I saw this tangle of supply lines and a gauge with an adjustment knob.  There is a similar gauge and adjustment knob on the passenger side of the generator.  What are these for?  And are these air tanks for the air ride HWH system?

Both are air regulators.
The one on the passenger side is probably for air step.

The Front air regulator supplies air from the front brake tank to the front air suspension manifold.
Pressure should be 50-60 lbs.

They put a regulator in the front circuit so that when we go into travel mode, the front end
(which is lighter) doesn't raise faster than the rear and confuse us
into thinking we're ready to travel before the rear is at travel height!

Just a couple of other things to tack on to Barrys answer.

The air regulators (the gauge and knob part) can be purchased at Lowes when the time comes to replace them, and it will  ;)  They tend to fail with air escaping out of the turn knob end where you adjust the air pressure, easy change out.

Also at the top of your your picture is a rectangular block, this is the HWH front manifold.  It has the solenoids to add / dump air to the front bags.  That is also where you might find a mud dabber build a nest and plug the exhaust ports.

Along the same line, can you identify the air manifold in this photo? This is taken by sticking my camera inside the front bay on the drivers side and is just past the steering column u-joint. I have had leaks from line 64 and 14. I can stop the leaks by pushing the lines back into the quick connect fitting. It almost seems like the nylon tie-wrap that holds a bunch of these lines is so tight that when I drive it pulls on these lines. I tried to relieve that a couple days ago and will recheck it after we next move.

Dick,
This air diagram shows those 2 lines 64 & 14 & where they go.

I see that. Maybe when we see you, you can help me understand what I see on that diagram.
I could not find line 20 on the diagram.
Can you tell me what that manifold does?

The manifold is actually the bottom of your treadle valve, aka brake pedal.

My schematics also so that it should be line 21 but the hose is physically labeled 20 on our coach as well ... 64/65/14/21/49/26 all go to that area, I can see 64/65/14/20 but need to see if I can get a shot of 49 and 26 as well ..... at the bottom of the valve there is an exhaust port cover by a rubber/silicone diaphragm, you can hear that open when you let off the break pedal, oh I mean treadle valve  :)

Dick - just checking; were you able to resolve the strain on these lines?

I think so. After the last three moves, I have checked and those connections are not leaking. I will keep my fingers crossed.  :D
