I recently bought an MC-5A. When i bled the water out of the front air tanks, I got a lot of water. I've replaced the petcocks with spitter valves that I can reach from either side of the coach so there will never be that much water in there again. If there was that much water in the tanks, how much water is sitting in the bottoms of the air bags? Assuming a similar amount, how do I get the water out of them? Is there enough oil in the water that the bottoms of the air bag chambers won't rust?
