Please note this cylinder is much taller than a traditional 30 lb steel cylinder. For most RV owners it is not a correct replacement for your steel 30 lb tank unless you have approximately 7 inches of additional height clearance. It will not fit in a compartment or cover designed for 30 lb steel cylinders. That’s why we specifically imported our new 22 lb cylinder for the RV industry. Since introducing our 22 lb cylinder we are unsure if there is sufficient demand to produce more cylinders in this 31 lb size. Information on our 22 lb cylinder is available here. If your RV currently uses 40 lb steel cylinders and our 22 lb cylinder doesn’t meet your needs, please take a moment and send us feedback using our contact form.
This cylinder was never available from any retailer or any other source. A limited quantity were produced and sold directly through this website as a market test.
Viking Cylinders products are lighter, safer, and more durable than any other product currently on the market. The 31-pound vapor cylinder is our largest cylinder available—it holds more than twice the propane that you will get from many propane exchange companies and still weights less than the standard 20-pound steel tank.
Note: this size cylinder will not fit under most propane grills.
