Black Plastic Tank-like Object?

At the risk of providing a good chuckle for the day, I was under my Winnebago Aspect (Class C, Ford E-450) yesterday, in the vicinity of the slideout, when I observed a round black plastic canister-like object secured to the chassis rail. It was about 8" in diameter and around 2' long with several plastic tubes sprouting from it. The slide-out is electric and the levelling jacks are HWH hydraulic. I had another appointment to go to so I didn't have time to trace down where the tubes went. To be honest, I was trying to locate the hydraulic motor and reservoir for the levellers - but without success. I plan to do a "sound" test, with my son listening, possibly tonight. Can anyone hazard a guess as to what in heck the black canister is for???

Probably the evap canister for emissions. It collects the gasoline vapors from the gas tank and sends them to the engine to be burned when command by the ECM.

The Evaporative Emissions Control (EVAP) system absorbs fuel vapors and, during engine operation, releases them into the engine intake where they mix with the incoming air-fuel mixture.

When the engine is not operating fuel vapors are transferred from the fuel tank, throttle body and intake manifold to the charcoal canister where they are stored. When the engine is running, the fuel vapors are purged from the canister by the purge control valve. The gasses are consumed in the normal combustion process.

Another gadget to save us from ourselves. So it a good thing.

Another person I had talked to locally suggested that it might have something to do with the emissions systems - but your explanation was very educational and appreciated! Many thanks.
