Onboard Propane Power for Your RV or Van Adventures

Keep your RV or van ready for every adventure with the Flame King 29.3 Gallon ASME Horizontal Propane Tank. From cooking and heating to powering appliances on the road, this tank gives you dependable propane supply trip after trip.

Accurate Gauge for Peace of Mind

Never get caught off guard - the built-in remote-ready propane gauge lets you check your fuel level at a glance or connect it to your RV's tank monitoring system (twin site dial sold separately).

Safe, Hassle-Free Refills

Your tank arrives EMPTY, vacuum-purged, and ready to fill right away - saving you time and the cost of purging. Constructed from high-grade welded steel with a durable powder-coated finish, it's designed to withstand the elements mile after mile.

ASME Advantage

Built to strict ASME specifications in ISO 9002-certified facilities, each tank is x-ray and hydrostatic tested for safety and durability. Plus, unlike DOT cylinders, your ASME tank doesn't need recertification after 12 years - giving you long-term confidence with less hassle.

Premium Valves & Easy Installation

Fitted with a fill valve, service valve, and pressure relief valve for safe, reliable fuel flow. Mounts easily under your RV, van, camper, or trailer with sturdy welded brackets. (Mounting bracket bolt hole centers measure 46 inches apart, with three holes per bracket, each about 1" x 1/2" for flexible mounting.)
