IDK, everyone has different use patterns for their RV.
In the winter months the challenge is having enough AH to power the furnace. After that then it is enough propane to power the furnace, HW, stove and fridge.
IMHO: the fridge is the LEAST propane use item in a camper.
Personally, I no longer use the HW heater. While the furnace gets used more if the weather drives us inside (in the winter) otherwise it is only used at night and 1st thing in the AM to get the 'chill' off.
So my propane use in the summer is mostly stove (cooking/coffee) and fridge. I'll generally need to fill 1 5gal propane tank 1 maybe 2x a year.
My fridge is a 2014 - I can hear the gas valve open and gas flow while it is running - which is not all that often.
