I would be very suspect and continue the investigation.

When I picked up my brand new Fuzion it had the Grey and Black tank labels on the pull handles in the hook-up access panel REVERSED! It also had the labels for my two fuel tanks (accessory fill station and generator) reversed as well. Mine must have completed the assembly line of a Friday afternoon or something.

Anyway, I wouldn't rule out labels being incorrect and I wouldn't rule out sensors being incorrectly mapped on your display either (although less likely). On the plus side, you don't have to necessarily solve this mystery now as the more you camp in the unit the more obvious it will become how things are plumbed. Good luck!
