I'm thinking that the rust may not have been caused only by moisture in the compressed air. It may have partially come from outside. Recall historically how intolerant ARB solenoids have been to dust. I put a sintered bronze pneumatic muffler/filter in their exhaust ports.
On my old 4rnnr I used one of the ARB solenoids as an unloader for the Puma OBA compressor. Since I used pneumatic toggle valves to operate the ARBs I had two spare solenoid valves. I used one of those muffler/filters in that ARB solenoid's exhaust port. In the 2+ years that I drove that truck (it was my DD and the only horn was air, so the compressor got cycled at least once a day) I never had a problem. I'm in contact with the father of its current owner and I've heard of no problems in the ~2 years that she's been driving it.
I'm pressure that Mike knows what these muffler/filters are, but for those wondering they look like your old Q-Jet's fuel filter, only with threads on one end.

I've found them to be very effective at keeping stuff out of things while still allowing air flow.

In my mind all that I have done is keep it properly maintained and when something needs attention I try to think through any possible ways to improve rather than just do quick repairs. To me it is just a nice and well-maintained coach, but for some reason I have had a lot of questions about it lately. Questions like the condition when we purchased it, what we did to in early on and what we have done to it more recently so while I had the coach out of the shop last week I did a walkaround video of it. It's long, but I hope I covered everything that people were asking about.
