I have a 2004 Tiffin Phaeton on a Freightliner chassis. My question is how long ( hours/days) should it take before the airbags bleed down. When should I be concerned about a leak. If it bleeds down ...
The air bags should stay up even if the dash gauges show 0 as they on a separate system controlled by three ride height valves. Even with air leveling mine will stay up for a month. If your coach goes down over night the good news is it's a big enough leak that you should be able to find it. Could be on the exhaust of the ride height valve that may require you to put your finger over it to see if it's leaking. I wonder how long...?
