After a long stretch of icy, frigid winter weather, spring temperatures are finally rolling into Pennsylvania. Budding trees, blooming flowers and longer daylight hours can only mean one thing: camping season is calling. Families and friends across the Keystone State are getting ready to rev up their RVs and map out some weekends under the stars.
But before you pack the s’mores fixings, fishing gear and bug spray and head to your favorite campground or national park, there’s one important item to check off your list — filling your camper’s propane tanks. Propane keeps your RV comfortable and functional, powering many of the conveniences that make camping feel like a true home away from home.
In this article, we’ll walk through how campers use propane and the types of propane tanks you’re most likely to find on your RV.
Propane is an ideal fuel for campers because it’s efficient, dependable and easy to transport.
Campers use propane to fuel space heaters, ensuring cozy evenings when temperatures dip. It also powers water heaters for warm showers after a long day outdoors. Many RV stoves, ovens and outdoor grills rely on propane, too.
Another big advantage? Propane is stored as a liquid under pressure in secure tanks and cylinders, making it compact and convenient to carry. That portability is a big reason it’s such a popular energy choice for recreational vehicles.
The size and style of propane tank your camper uses depends on the type of RV you have and how much fuel you typically need.
Removable DOT Cylinders
Smaller campers and travel trailers often use portable cylinders regulated by the U.S. Department of Transportation (DOT). These tanks can be detached from the vehicle and taken to a refill or exchange location when empty.
Because they’re removable, they’re relatively simple to refill but hold less fuel than larger tanks. The most common sizes are 20-pound cylinders (similar to a standard grill tank), along with 30- to 33-pound and 40-pound options. Many campers carry two cylinders to extend their time between refills.
Built-In ASME Tanks
Larger motorhomes frequently feature permanently mounted propane tanks. These are manufactured to standards set by the American Society of Mechanical Engineers (ASME). Unlike portable cylinders, these tanks stay attached to the vehicle and are typically installed along the exterior frame.
ASME tanks often range from about 20 pounds up to 100 pounds or more, depending on the size of the motorhome. When it’s time to refill, you’ll need to visit a propane refill station equipped to service RVs.
Safety should always be part of your camping checklist. Before hitting the road, inspect your propane tanks for signs of rust, corrosion or visible damage. Check hoses and connections for wear or cracking.
Never transport a loose propane cylinder inside your camper, and always turn off the propane supply while driving. When refilling, shut off all appliances, pilot lights and ignition sources. It’s also wise to have working smoke, carbon monoxide and propane gas detectors installed in your RV, along with an appropriate fire extinguisher.
If you ever suspect a leak, exit the camper immediately, avoid open flames and contact emergency services from a safe distance.
