Don, there are 4 tanks. Lanyards make for easy draining.

My assumption is that there are three separate (at least) air storage systems on my Bird. One for brakes, one for suspension, and one for auxiliary, with the latter including the step. That one is the fastest leaker on mine. The assumption is based on: The front/rear gauge, which is the brakes, stays up. The air bags stay inflated. The low air indicator comes on in just a few
minutes without air, and the step comes out.

It is possible, of course, that there are only two, and the bags are actually on the same system but stay up due to check valves; that does not change the fact that the aux system loses air fairly rapidly. I know I get some loss around the air dump valves. There are lots of other places, such as air waste dump valves, bulk oil fill, step cover, freshwater purge, air-extended driving lights, and probably more I can't think of.
