Air suspension

[Billy Casper]

I have air suspension on my van which allows me to set the pressure via switches in the cab. I have absolutely no clue what pressure it should be set at, or if i should have any air in pressure at all, particularly when parked up.
I'm currently uprating my van and it seems to be something that has eased the process but I'm still not sure how I'm supposed to get the best use out of it.
Can anyone give me guidance?

I don't know what system you have but generally do not let them go flat / low pressure as the bags can be damaged.

If you can see a name or label then let us know and someone will know likely best pressures.
