Rear Air Ride

It's 75 this evening... Cloudy & calm, Worked a bunch on the bus this weekend!
Sitting back in my lawn chair recliner, petting my bus... (It has a calming effect)

I dumped my air tank earlier, all stages were wet!

Now my air bags are leaking down... About every 5-10 minutes, I hear the springs creak.
Should I start the engine and build pressure back up, or just dump the air bags?

Not sure what I'm gonna do when I'm full timing it

Mine empty in like 15 mins. Yeah, I gotta leaky airbag.
Jack stands under the rear axle would solve your sagging issues. Set em maybe an inch low and once you fire up the bus and it airs up you can pull em right out.

I suspect this is why my rig doesn't hold air pressure for more than a few days. I'm wondering if it's something I need to address or not

Losing air, while not running, is pretty typical. I put over 100k miles on a brand new $420K Prevost that would lose its air in 36-48 hours. I believe that RVs with air suspensions and leveling have a 12V compressor to maintain air pressure.

I'm still puzzled why all 3 stages of my air tank blew out moisture...

When I opened them a few weeks ago for my first time, at least a cup of sludge came out of first stage.

Has anybody tried the cabled pull down tank drains?

Soon, I won't be on concrete with a creeper and I've got a protected area I can put the cable ends

Thanks to the severely dry rotted and leaking driver side rear air bag, mine loses its pressure in maybe 20 minutes. Definitely needs to be fixed sooner than later. I don't use it on the road anymore. Just around the property.

How do you drain the tanks? I've never tried

Yours are on the drivers side just forward of the middle of the bus. There's a big tank with three drain valves on the bottom. Just go under there once you've shut it down, and let the air/moisture out.

Cautiously!

Make sure you know which way the outlet is pointed!
Air, moisture, and sludge blows out
