How long will LP last for fridge cooling?
I plan to park my motorhome in dry storage for 2 weeks and don't want to empty our fridge & freezer. Does anyone know how long a 50 gallon LP tank will last running the fridge & freezer only?

There's approximately 91,500 btu's in a gallon of propane.
Say your fridge burns 2400 btus an hour (varies depending on size of fridge).
So one gallon of propane will last about 38 hrs. However that's if the refrigerator runs constantly.
Say it runs for 8 hours out of a 24 hr. period a gallon of propane should last about 5 days. 50 gallons------250 days
Now that fridge also needs that 12V DC for the control circuit. That and other parasitic DC loads (LP Detector, Emergency shutoff Solenoid, clocks/radio, etc.) will draw battery down in about a week.....then no more fridge working.
Couple of days without being on.......bring a large trash bag and cleaning supplies.
That is IF the LP continues to work without having some kind of problem
I'm all for operating fridge on LP......I do so when traveling etc.
BUT unattended for 2 weeks.........not such a good idea.
