You are making quit an assumption that it had been improperly parked which caused the corrosion. With your descriptions, I bet it had been exposed to sea water or salt treated roads.

Sea salt, no, plated Ohio and bought local so no sea. Not sure where it was parked but there was no evidence (that I saw) of salt or CaCl corrosion because there was no white residue thats associated with road salt anywhere I looked. Don't believe the owner washed the underside off, least it didn't appear to be ever washed.

The problem with your reasoning:
1. Where purchased and the license plate have nothing to do where the RV may have been driven.
2. You allege that the extreme moisture of the earth was captured under the RV and caused the rust. If that were the cause, I ask you to explain why RV's in Houston, Texas, just for example, don't exhibit the same rust. Humidity levels in Houston reach 90% for extended periods of time.
3. The sodium chloride and other chemicals used in treating roads reacts with the metal causing the rust. I think there is a chemical process that would consume the residue you didn't see. If the residue remained on the metal, how would it ever cause rust? There has to be a reaction.

Candidly, I really don't care. I only posted what I observed on this unit and what the tech told me and showed me.

I do know if, I was contemplating purchasing one (which I'm not because a road wagon don't fit my lifestyle), I'd be looking underneath as well as inside and certainly doing a spectroscopic analysis of all the fluids.

The corrosion I observed and what the tech showed me (inside the ATA plumbing) had to be caused by moisture and sitting somewhere the moisture was allowed to condense on those surfaces.

First time I've ever seen internal corrosion like that. I see carbon buildup in intake runners from EGR but never rust.

Think if I did buy one, new one, I'd fluid film the chassis before it went anywhere.
