Travel trailer refrigerator question?

I have a 2010 wildwood travel trailer and I am planning on going on a long road trip. It comes with 2 thirty gallon propane tanks that can run the refrigerator. My question is how long can my 2 tanks run the refrigerator?Travel trailer refrigerator question?
Propane refrigerators are relatively economical for consumption. If you can find the rating plate on the appliance it should list the btu's of the burner. It probably is no more than about 2500 btu's...



The quick and dirty formula for consumption is that 100,000 btu's will burn 1 gallon in 1 hour. So 100,000 梅 2500 = 40. You are going to use 1 gallon of propane every 40 hours. A gallon of propane is 4.2 Lbs roughly, so you have about 7 gallons of propane in a 30lb cylinder. 14 gallons ( 2 cylinders ) x 40 hours = 560 hours...divided by 24 hours is just over 23.



So...after all that confusing math...you have about 3 weeks supply for your refrigerator if it is running under full load all the time. I would say you easily have a months worth of propane supply there.Travel trailer refrigerator question?
Can I assume you meant 30 pound and not 30 gallon? 30 pound cylinders are typical on most larger travel trailers and fifth wheels. A 30 pound cylinder will hold 7 gallons when filled. That's about 80% of its total volume but propane cylinders are not filled completely to allow for expansion of the gas at warmer temperatures.



If you're just running the refrigerator then your two full cylinders will last a two to three months or more. But most times you will also be using the stove top, oven and furnace. The furnace being the biggest consumer. In the winter I can go through two cylinders in eight days. In the summer, not using the furnace much or at all, I can go a month or more.



Keep in mind there will always be places along your way where you can refill the cylinders. Many campgrounds and RV parks sell it as well as gas stations. So as long as you plan ahead, just a little, you won't have to worry about running out.



Generally, RV refrigerators are designed to work on either propane or 120 volts however the control board needs 12v to operate.

I thought the fridge runs off of 12 volts taken from the trailer harness or the trailer battery.

The propane runs the heater (furnace) and the stove/oven
