Thanks Chance--so if I understand correctly, we dump the black tank first, then the grey tank AFTER the black since it goes through the same hose--the grey water "cleans" the hose (kind of)--then also run the nonpotable water through the hose when we are done with the grey--correct? Also thanks so much for the thought of dumping even if we are partially full--we definitely would NOT have thought of that! I am sure we will make plenty of mistakes since it's our first time, but this seems like a really good one NOT to make!
