This is a difficult question to answer as there are so many variables. For example, if you tried to run the fridge off 12 volts it would drain the battery in a couple hours. Also, we don't know the amp hours of the battery that comes with the RV. A good group 24 battery will give you 70 to 80 amp hours, a group 27 - 80 to 105 amp hours and a group 31 - 95 to 125 amp hours.
I'm going to assume that the RV you are renting does not have a generator nor an inverter. Therefore forget about using the microwave, TV or electric coffee maker. I will also assume that the stove, furnace, water heater and fridge all work off of propane.
So if you ran four 1.2 Amp light bulbs for 3 hours per day that's 18 amps hours. If the water pump only ran for 20 minutes each day that would be 3 amp hours and if your furnace fan only ran for 2 hours per day that would be 6 amp hours for a total of 27 amp hours per day. Thus depending on the battery you might or might not make it for 3 nights.
Bottom line it all depends on the type and condition of your battery and your daily consumption.
Hope this helps.
