With the weather warming up in Northwest and Central Ohio and West-Central Indiana, plenty of families are thinking about outdoor adventures. Whether you’re planning an extended tour of National Parks or a pleasant weekend fishing and hiking at your local campground, having your RV’s propane tanks filled beforehand will ensure a safe and comfortable outing.
You can drop by Mercer Landmark Energy’s Coldwater location to get your camper tanks refilled safely and for less than you’d pay at an exchange.
An RV is your home away from home when you’re in the great outdoors, and your RV’s propane tanks are the essential energy supply to ensure you’re as comfortable as possible. Propane is an exceptionally versatile fuel that travels safely in pressurized containers. RVs use propane to power climate control equipment, water heaters, cooking appliances and other equipment.
The propane tank your RV uses depends on the type of camper you own and how it is designed to store fuel. Larger motorhomes typically use permanently mounted ASME tanks. These tanks, built to standards set by the American Society of Mechanical Engineers, are fixed to the exterior of the vehicle and are not removable. ASME tanks for campers commonly range from 20 to 100 pounds and must be refilled at a propane station equipped to service vehicles.
Smaller travel trailers, pop-up campers and lightweight RVs often use portable DOT cylinders. DOT stands for Department of Transportation. These removable tanks can be detached for convenient refilling or exchange. Common cylinder sizes include 20-pound, 33-pound and 40-pound tanks, giving campers flexible fueling options on the road.
When it’s time to get more propane for your RV, we strongly recommend that you go to an experienced propane provider with appropriate equipment for the job. Our Coldwater, Ohio, location is the provider of choice for RV and motorhome owners in this region. Our team will fill your DOT or ASME tanks at a fair, affordable rate. We can also inspect your tanks, cylinders, hoses and connections to ensure they are in safe, durable condition.
