Propane gas used in truck campers is also known as LPG or LP gas.   The gas is a non-toxic, colorless, clean-burning, odorless mixture of flammable hydrocarbon gases used for heating, cooking, and cooling in refrigerators.

Thus, to overcome the odorless features, Ethanethiol is added to LPG so you can easily detect leaks. Should there be an LPG leak, the gas being heavier than air will flow along the floor of the truck camper.

The most common LPG container used in RVs is the 20- or 30-pound cylinders. These cylinders are mounted either horizontal or vertical in the RV and are not interchanged.

Cylinders are subjected to the twelve-year and five-year interval requirement for recertification.

These regulations are designed for safety and protection in determining if a cylinder is safe and legal to be filled and refilled. As a truck camper owner, you must be aware of these interval requirements.

The date that the cylinder was manufacture is stamped on the protective collar, also called the neck ring.

For example, a cylinder manufactured in July 2005 needs to be re-certified before July 2017 and every five years thereafter. THE LPG CONTAINER The collar is also stamped with the empty weight of the cylinder in pounds known at TW (tare weight).

TW for a vertical cylinder is about 24 pounds and is generally called “20 pounders,” while horizontal cylinders have a TW of 27 pounds.

A “20 pounder,” when filled to the legal capacity of 80%, will weigh about 38 pounds.
