We are attempting our second boon docking with a Tab 320 CsS (2018) and have upgraded to a marine battery. How long will this last us, and is it okay to charge on our car (we do this when traveling).

    When you say marine battery do you mean a lead acid, AGM or lithium?  What is your amp rating?  Do you have solar? If you have a charge wire with your 7 pin, you can charge, but depending on your TV, it may be limited.

    Show us a picture or link to the battery. Tell us the year and model of the trailer.  What fridge do you have?  A 2 way fridge?  Or a 3 way fridge that can run on propane?

    A CSS has a 12V frig.  No propane.

    I budget about 30ah power consumption per day, 40ah when the ambient temperature is really high (90+). What is the amp hour capacity of your battery? Do you have any solar panels? 
    Your tow vehicle may provide some power to the T@B battery, but if the fridge is running the net gain might be zero.
