RV propane tanks store the fuel that powers your furnace, water heater, refrigerator, and cooking appliances. Whether you need a replacement DOT cylinder (the portable tanks on your trailer tongue) or an ASME tank (permanently mounted on motorhomes), proper tank selection ensures safe, reliable LP gas supply. We carry tanks in standard RV sizes along with mounting hardware and regulator systems.

What to Know Before You Buy

• DOT cylinders (vertical portable tanks) must be transported upright; ASME tanks (horizontal permanent tanks) are mounted to the RV frame.
• Tank sizes are rated by water capacity (e.g., 20 lb, 30 lb)—this indicates the tank's weight when full of propane.
• New tanks must be purged before first fill to remove air and moisture—ask about this when you buy.
• Tanks require recertification after 12 years (DOT cylinders) or inspection at intervals (ASME tanks).
