On my fifth wheel, I found the airline has melted across the exhaust. We've got to leave tomorrow morning. We probably were running on one airbag on our last trip. Now that Ive discovered the flat air...
It depends on the type of air bags. Mine are Airlift w/o the bumper. They say I must have 5# in them to prevent damage! The ones with the internal bumper can be run "flat"
