Hitting the road in an RV is an excellent way to see the country while keeping the comforts of home. While the vehicle itself runs on diesel or gas, it’s common for many of the fixtures on the interior to utilize propane. Here’s a closer look at how the fuel source works and what to do when you run out. 

What Uses Propane in an RV?

Every vehicle is different, but it’s common for HVAC systems — furnaces in particular — to use propane. RV water heaters are also frequently connected to the fuel source as are gas stovetops and attached exterior grills. In many cases, refrigerators also have a switch that allows them to use either electric or propane so that drivers can keep perishables safe when off grid or during a power outage. 

Typically, one or two propane tanks are attached to the exterior of the RV and connect to a fuel system. When the valve is opened, it allows the gas to enter a supply hose that connects to the various fixtures and appliances that rely on it. While tanks can be left on while in motion, it’s usually considered safest to close the valve prior to moving the RV. 

How to Fill a Propane Tank

Once a tank nears 20% capacity, it’s time to get it filled or replaced. Some RVs use 20-gallon propane cylinders, which are easy to remove. As a result, it’s common to exchange them at gas stations for a new full tank as its incredibly convenient and cost of the tank is waived if providing a (near) empty one. 

Larger holding containers — 30- or 40-gallon tanks — are usually refilled instead. In such situations, a fuel provider can inspect the tank for safety and then fill it up. When it comes to propane, a full tank is around 80% as the fuel expands with heat.
