How big is your propane tank....gallons?
What fridge brand/model?
Gallon of propane has 91,500btu
A very large RV fridge has a 2200btu/hr burner
Furnace....20,000 --42,000btu/hr
Water heater....10,000-12,000btu/hr
Stove top burners.....5,000--9,000 btu/hr
Oven......1200--1500btu/hr
Look up your RV propane appliance btu/hr ratings....add them up
That is how much propane would be burned if ALL where in operation for a FULL Hour
Do some research on your items so you can get an idea on requirements
THen over time you will see just how much is used/needed for YOUR usage
Just a quick check a 2013 Vista 26 has an 18 gal capacity tank
80% is 14.4 gal
