dry camping

I need to dry camp one night in Jasper Nat Park. Only want to keep the refrigerator running for one day. Will the battery last 18hrs. Need advice

Is your refrigerator running off of propane or 12V? If propane, the system uses only a tiny bit of electricity to keep the gas flowing. It will run for days on battery in that case.

Not if that fridge's climate control heating element has not been turned off, it won't. :R The best "advice", which the OP asked for, is to make sure this element is off whenever running on battery power.
