Air Dump Switch/Valves
My 2019 Entegra Reatta has an Equalizer leveling system that includes automatic air dump / inflate, but does not have a separate air dump switch.
I've had a separate switch on other coaches and frankly I miss it. Has anyone installed a dump switch on their coach?

I have the equalizer levelling system without a separate dump switch. With the engine off (ignition on), I hit auto level and immediately retract the jacks. It dumps the air but not as elegant as a separate switch. I’m interested in this too!

I'm reading that the dump is automatically activated by 12v applied to the gray wire exiting the Equalizer control module. Can it really be that simple?
If so, a momentary on switch would do the trick. Can anyone confirm this approach?
The alternative would seem to be a set of valves tee'd into each HCV ...

I would like to install a switch to just dump the rear axle so I can load my motorcycle easier. I too would like info on installing a separate switch. I assume I would need a diode in the circuit so it doesn't back feed to the front valve.

I'm with you on the diode, although the amperage is an open question ...
Absent any confirmation elsewhere, I'll see if I can test the theory in the next week or so ...

Regarding air dump options, has anybody done the following?
Given:
HWH Leveling System
Airbag System on a Spartan K2 Chassis (not sure this matters).
Coach is fully aired up at drive height. Engine is running.
1. Shut off engine and set key to accessory.
2. Press "Auto Level" Button on HWH Remote Control Head (air dump will immediately initiate).
3. Turn ignition key off before jacks start to deploy.
Useful for:
1. Loading heavy equipment into coach.
2. Minimizing height under a questionable bridge (restart engine and promptly drive straight under the short distance bridge without turning wheel and damaging front wheel fairings).

Search the internet for air-ride bus Kneeling option. That is on the front of municipal bus's, but no reason it could not be for the rear instead.
