I've been running some tests on my airbags. I start the MH up and when my front and rear air gages show full I shut the MH down and then check the gages several times over a few days. The lowest the gages got were just below 65psi on both gages and this is with the jacks not extended. So I'm wondering if my problem is with the airbags or with the system that feeds them the air. Any thoughts out there???
