Just about to embark on first extended outing with 2015 California bought last month and want to use fridge as temporary freezer for a two day trip where we won't have external power overnight for 2 nights when engine will be off. Guide says 'the additional battery will discharge if refrigerator box is used for a long period if the engine is switched off and the 230v connection is not used' . Any idea how long is 'long? Thanks.
