I am in my shop where MH is stored. Went underneath and had a look.
It's a reservoir for the rear airbags. Supply line going into tank, and a line going out to each rear air bag.
Opening the petcocks lowers coach as it dumps air from rear bags.

Next question is it something that needs to be left alone and no water to drain?

I opened up both petcocks for a bit, no moisture came out. But the coach did lower as air was released from air bags.
This small reservoir will be plumbed in after the primary and secondary tanks that are in the front. I have cables hooked to the drains on these tanks, and can access them from front right wheel well.

That's what I love about this forum, the educational benefits. I'd like to ask a question to anyone who can answer.
Why is this extra tank in the system? I'm familiar with the air ride system on commercial trucks and some luxury automotive applications.
I've never encountered an air tank between the height control valve and the air springs.
What is it's purpose, because it can't be additional air storage at this location.

Isn't your chassis a Liberty?

You have a Spartan Liberty. That is what the LE stands for. Liberty Edition. The Spartan Liberty I am told is one of the strongest chassis ever built. That is why you have a 15000 tow hitch compared to what the Freightliner has. Starting
in 2005, Revolutions were made with Spartan chassis and with Spartan Liberty chassis. About $20000 more...

Yup, be proud of that Spartan Liberty chassis. MM ain't no slouch either, but the chassis (and towing capacity) was definitely a selling point for me. I am assuming cost was a factor as to why AC went back to freightliner, yet many other high end models still use Spartan.
And yes, I have that tank, opened the petcocks once and no water.... I don't drain those nearly as frequently as my front tanks that have lanyards on them.

There is no such thing as a "spartan liberty chassis" the name liberty comes from Fleetwood as I stated before mine is a MM.

Hi Rooster,
If you go to Fleetwood's home page and open the 2005 Revolution brochure, you will see that on every page they state the differences between a Revolution and a Revolution LE. They refer many times to the Liberty chassis of the LE. That was the first year of the LE, and the regular Rev was also being sold.
Also, if you call Fleetwood, they will explain the differences. One difference is that the regular Revolution only has three jacks, the LE has four, because the regular Rev could not tolerate the twisting.
