Re: Air tanks questions...

The air tanks are made of pretty thick material, so a little surface rust would not be a big concern. What the inside of the tank looks like is another matter. I suspect that most owners would not worry about the air tanks unless they (the tanks) developed a leak. We have had a couple members who replaced tanks due to desiccant powder contamination, but that's another subject entirely.
If you ever need a new tank, they are available and surprisingly not real expensive. I believe Mike (Pamela & Mike on the Forum) can point you to the source for a new one, and so can the factory.
The air valves and other components require periodic maintenance, just like everything else. There is no schedule...how often depends on how the coach is used, and how dry the air system is kept. Some of the air components, like check valves, can be disassembled, cleaned, and then put back in service. Some components, like the air dryer and the PP-1 valve, can be rebuilt with a kit.
Bendix PP-1 Repair Kit.
In some cases, like the D2 governor, the best/easiest solution is to simply replace the component whenever it starts to act up.
