Thanks for all the ideas and suggestions. I've located the leak in the door seal as it appears something got caught and cut the seal near the top of the door. It's possible it just a weathered split but it appears to be a slice across the whole seal. I'm going to try a rubber patch and see if that works. Meanwhile, I've clamped off the hose that feeds the seal and the coach appears to be holding air. That said, I haven't driven it yet so I may have other issues. I'll have the parking brake checked when I have the front tank replaced. I've seen how fast the coach drops when losing air and I don't have the equipment to properly block the chassis, so I don't go underneath it anymore.....Thanks again to everyone and I hope everyone has a safe and enjoyable New Years celebration....Dennis
An easy way to check for the parking brake is to build up the air shut the engine off put chocks or blocks in front and rear of wheels release the park brake and just walk around and listen. You will hear the air leak from outside without going under.
