Dumping rear air bags on M2

[Joe II]

In the meantime while you're waiting to either install the switch or get one installed. You can always cycle your parking brake a bunch of times and run your air down low enough that the bags drop.

They changed that on the S2 chassis, the suspension circuit is isolated now. You can pump the brakes until the tanks are empty and the suspension stays full. Adding the air dump is probably the best mod I ever did.

Another approach that I know some Renegade owners use is to just raise the back of the coach so the levelers let the air out of the bags. Then lower the back down (bags are now empty) and level.

This usually takes several cycles to dump everything and you take a chance of overheating the pump if you run it to long without a cooling down period.


Another thing is if you have the Equalizer system, your air dump can be wiring into it so it is all automatic, when you start your leveling system it will dump your air first and then start leveling. I know several owners that have wired it up that way.

On the Valencia and Verona you do not have to cycle the rear to dump the air bags. When you raise the rear, the leveler automatically starts letting air out as it thinks it is too high. It will continue doing so until it reaches the level it wants, which it can't do because the frame is being held up by the jacks. Run it down to 50-60 pounds, raise the jacks just until they are off the ground, and level. No cycling. I have a friend who get out of his coach with his iPad, using the bluetooth Equalizer control and Levelmate pro, and does all of this pretty efficiently walking around the outside of the coach.

I also intentionally did not wire mine into the Equalizer system because then they would always dump. I have run across campsites where I do not want the rear bags dumped. Wiring to a dump switch gives you the ability to control when they dump.

When I asked what the changes from a 2021 to a 2022 Verona are, I was told Renegade added the dump switch.

This is exactly what I do. Works perfectly and keeps it simple.
