2008 keystone passport 285rl fridge
I won't have AC electric avail where I am taking my camper... Do I need any source of power for my fridge to run off propane? Also how many days would a propane bottle last if fridge was kept shut...

Taking a wild guess, if you have a full 20 pound bottle it will go at least 3 weeks on propane but you still need a fully charged house battery because it needs 12 volts to operate though the current drain is quite low.
I ran my Dometic on a test run, straight propane, full bottle and house batteries (I have 2) a full month before the bottle ran out. Batteries never did.
To lessen the gas usage. pre cool the unit before leaving on 110 volt shore power and load the fridge with pre-cooled food and the freezer with frozen bottled water, which, you should always do anyway. An ammonia fridge needs pre cooled food as they will struggle to cool down warm items.
