Mine also has a Winter Freeze Guard port at the top for handling winterization antifreeze. My onboard water tank fill is in a separate compartment to the right of the main control panel. At the risk of pointing out the obvious, the outdoor "shower" is also at the very top of the main control board.
We did experience some residual(leakage)from one of the gray tanks when we first opened the main sewer. Anyone else?
We have had no issue with our fireplace getting loud. If I had any complaint it's that it heats up the living area very quickly! Got to keep an eye on the thermostat.
Sturgis? Wow! What a madman! Got reservations? (I hope)
