I've been chasing an air, leak for those of you who haven't seen my previous posts, and so far no luck in pinning it down. Now I noticed, when I press the air dump button and bring the pressure to 0psi, the front airbags seem to be still inflated! They are still hard to the touch and don't feel or look like the rear bags which are most definitely deflated. Also, the height of the coach off the ground doesn't change. What does the air dump solenoid/valve look like and has anyone else ever experienced this?
