All I can say is Thanks! What you wrote makes a lot of sense. I can help my crew use the tanks appropriately now.
The brochure showed four 40 gallon tanks (2 black, 2 grey) if I remember right. Do you know the volumes of the tanks?
By the way, I recognized your signature picture as soon as I saw it - your rig is one that I have seen before either on FROG or perhaps a dealer blog. Very nice looking setup! Maybe I am biased... but you have great taste in RVs.
