if your caravan is newish there is a feed from the battery on a permanent basis,this feeds your electronics on the fridge but does not operate the fridge cooling.if left on the battery could go flat sooner rather than later.
------------- the only silly question is the one you do not ask.
With the door open the fridge light would be on so the battery will eventually become flat.

For a licence dated 1997 or later you must add together the plated max weight of the caravan and trailer, if the total is 3500 or less you can tow it. You may even tow a caravan with a MAM greater than the cars unladen mass the restriction was removed in 2013
