Two black water tanks

I have a Dutchmen Kodiak that has a display showing levels for two black water tanks. When preparing for winter, do I need to make sure that both BWTs are filling up before dumping or is it good enough to get a fresh dump from the first one? I'm not sure how together these tanks are integrated.

TIA.

    @Campinfan - this makes sense. I have never seen the display show any volume in tank #2. I only have one toilet and one dump valve.

    And it a 221RBLS model.

    Thanks.

    Your display area may show two black tanks but you may only have one. My trailer is the same way. I believe they use the same control panel for many different floor plans. One of them might have a second toilet. If you have one toilet and I black tank handle outside, you only have one tank. Bet it says empty when you push the button.

    Two black tanks..? Do you have two toilets?
    Very strange...I have 2 gray water tanks which is not uncommon.
    Call Dutchman and get some clarification.

    Didn't know Kodiaks had 2 Black tanks.....which model do you have?

    Fill then dump all waste tanks so that no solids are left behind then after dumping pour some RV antifreeze down into waste tanks so dump valves are protected during winter storage.

    Drain fresh water tank completely.

    Drain plumbing system via low point drains...bypass/drain water heater
    Pump RV antifreeze thru plumbing system ....thru faucets/showers/toilet/low point drains etc.
    Pour some TRV antifreeze down sink/shower drains for 'P' traps
