Well, spent all day crawling around in the dirt under my MH spraying everything I could see connected to the air system. Found 2 small leaks, one easily fixed, the other is connected to the brake actuator and is in a really tight space but I should be able to get a wrench in there to hopefully tighten the connection tomorrow. These leaks are not the problem unfortunately. I think one of my airbags has a leak. The reason being, when siting still, the leak rate is approx 1 psi/minute. When driving it drops 25psi/minute. So i'm thinking a hole on the airbag would be partially sealed when sitting, but while driving the airbag is flexing and moving opening up the leak. I did spray the airbags today, but not very thoroughly as sections of them are difficult to reach. I will have to remove the wheel well liners to get to the airbags located in front of the wheels both front and back. Back under the MH tomorrow!
