You're description really helped me understand it. So I gained some education.
Over the years I have bought several campers from different dealers and it has always amazed me how ill-informed these dealers are about the various systems in these RV's. Every PDI I have had has had mis-information provided.
The best way to know what is good information and what is not is do your own research. Never take one person's explanation on how something works. Always look for the same answer from multiple sources.
That includes sites like this. There is much well-meaning information here that is inaccurate.
