Propane tanks, or cylinders, are one of the most important features of an RV. They provide resources necessary for comfort while on the road or camping in the middle of nowhere. If you’re unsure about propane tanks and their relation to RVs, here are some answers.

4 Common Questions About Propane

What are the different kinds of propane tanks?

There are two different types of tanks: ASME and DOT. ASME tanks are approved by the American Society of Engineers and are most commonly mounted to the frame of a motorized RV. DOT, or Department of Transportation, approved tanks are used in towable RVs, like fifth wheels, travel trailers, campers, and some smaller motorhomes. DOT tanks are removable, like BBQ grill tanks, while ASME tanks are not.

What are the different RV propane tank sizes?

DOT cylinders come in 20-, 30-, and 40-pound cylinders, which hold 5, 7, and 10 gallons, respectively. Class C motorhomes are equipped with ASME 20-pound cylinders, while larger Class A motorhomes may contain up to a 100-pound tank.

What items run on propane?

RVs now have more propane-friendly appliances. The furnace, water heater, refrigerator, and range can run on propane, and some models switch between propane and electric easily. Add a t-splitter or y-splitter to the valve to connect a second line that can run outside and be used with a grill or other propane device. Use the electrical option over propane if available. If something happens to the electrical, the propane provides a backup.

How do I determine how much is left in the tank?

Since ASME models are built into the RV, a gauge is usually on the dash or near the tank. Other models require a secondary gauge, which you can purchase and attach to the valve of the tank. You can also weigh it if you have access to a scale. There are also third-party products that check the tanks if you install sensors on the bottom of the tanks or use a handheld device that determines the level with ultrasound.
