I would guess you would stop for the night and set up a temporary camp. Put your refrigerator on propane then, or if at a campground with hookups, you could run it on AC, which will also charge the battery through the converter. If "dry" camping, you could connect a generator to the shore power cord and that would charge the trailer battery too.
Yes, the tow vehicle will send enough current to the trailer to help the trailer's battery run the fridge, but the battery will probably be run down some at the end of a day's drive. You need some way to recharge it when stopped. You COULD try to do it using the tow vehicle's alternator, if you put the fridge on propane, but that will be an inefficient process.
