There is a way to dump the air bags without auto-leveling. I did it already to check some jack blocks I made. You have to hit a button twice quickly, I just can't remember right now which button it is. I'll look at it again this afternoon.

I would like to say also that if I were you I would try to find a different option for getting your coach in your garage. I would be afraid that after starting the engine and backing up your bags will begin to fill again or they won't but you will not have brakes.

Good luck with everything.

Sorry guys but if you dump all the air in an air brake system you'll have nothing but brakes.

MC, Hopefully you mean this is a better option for you than some of the other suggestions, and not that those other suggestions were not worthy of consideration. Just thinking out loud.

I have a 400BH and a few times I've raised the jacks and drove away with no air filling the bags and I had breaks. I had to stop and retract jacks 3 times and then bags filled... But my point was I had breaks with no lift... Please don't plan on the fluke.

:Update:

I have an appointment with Freightliner this afternoon. They say "no problem", they can install a dump valve with a switch. Will be less than $200. Much cheaper than any of the other options

Semper Fi,
MC

Nice! Now you'll be a lowrider. Can they make it hop up and down just like the cool kids?

Make sure they install a light for when suspension dump is activated so you remember!

Semper Fi,

MC

One thing I would check before you spend the $200. When your bags are deflated the front of the coach drops more than the rear. I would dump the bags and take measurements before installing the dump valve.

Why not figure out what dumps the airbags and tie into that. Most air bags use a leveling valve to keep rig at certain level. To dump the values a 0.25" airline is plumbed into the leveling valve. As long as this 0.25 line has air applied to it the bags will drop. Remove the air from the line and the bags will inflate

Engage the levelers. After the air dumps manually raise them? There has to be a sweet spot that keeps automatic valve open. Listen for it
