Check the air fittings of the top of the bags for leakage, or leveling valves for air leaks. I use an ultrasonic leak detector to check for leaks. Others use soapy water out of a spray bottle and look for bubbles .
Should be push connectors on top of air bags, if so and they are leaking slip out the air line and cut off about 1/2" and reinstall, that should reseal the fitting and stop the leak. If not replace the fitting with a DOT push connect

Sounds like you could have a bad ride height valve or a dump valve leaking.
When you stop the coach after it has been running and aired up.
Listen for an air leak, if you cannot hear it then you need to use a spray bottle with soapy water.
Start spraying fittings and valves with soapy water.
I had an issue with front bags dropping quickly after stopping sometimes. The problem ended up being a rear ride height valve. Caught it one time after stopping and it was leaking badly.

Be careful under the coach. I use 12 ton jack stands when I crawl under. Especially if you are changing fittings. You may need to use ramps to drive on to to get the room you need.

If you hear air leaking anywhere that is an issue. Like I mentioned earlier, my front would drop quickly at times and it was a leak in the rear. Ride height valve above rear axle.
Not the best picture, but this is the rear ride height valve.
And a new one in its place.

Hi jimbison,
This will not show up on the air gauges because the engine is off. When the engine is turned on the air tanks will refill the air bags. There may be a slight movement of the dial. It is like when the bags are dumped so one can park and level. There are two ride height valves for the front and one for the rear.

We have a 04 Essex and we bought new and replaced all air bags last year because of cracks in the air bags. Remember you have a air line attachment in the front of the coach you can connect to a air compressor so that you don't have to have engine running to air up system. Using soapy water in a squirt bottle is a good way to find air leaks. You can put a 6x6 board under tires to get it up high enough so you can go under coach. Have 6 ton jack stands that I put 4 under frame for safety.

Front Air Bags
Sounds like your problem may be the same as what I had.
You can order from Spartan or other sources. I am guessing it is the same Haldex 90054007 search for this and pick your source.
Here is a place I purchase many of my parts from.

Keep in mind if you change this out on your own. Need to have heavy jack stands or blocking to keep yourself safe. Do not rely on your hydraulic jacks for safety.

Mine was a direct fit. Identical part.
If yours is different then may want to check with Spartan.
Make sure you can still get under with airbags dumped as all air will be emptied when you change the valve.
Also ride height may need to be reset, so it will need checked.
