Forest, I have also heard about that and have considered it for my coach....but would this be more than a toy? If you manage engine RPMS and keep your radiator clean, then shouldn't the system just take care of itself? In other words, when would you turn the fan on high?

Thanks to Richard, I understand the cooling system much better. (After having the coach 7 years its about time that I learned some stuff).
