A propane cylinder is a propane cylinder, right? Until now, maybe — because Viking Cylinders has a whole new take on this ubiquitous RV component with its line of lightweight, translucent composite propane cylinders. Using advanced technology, Viking has created the lightest and safest propane cylinder available, according to the company. For one thing, these cylinders incorporate ergonomic handles that make them much easier to lift and transport, and they won’t corrode or rust. Plus, you can actually see the propane fuel level. Viking Cylinders are a desirable alternative to heavy steel cylinders — and with 9 million units in circulation worldwide, they have an impressive safety record. The 22-pound size is made specifically for the RV industry.
