Where should all branch connections off the main gas supply line be made on a recreational vehicle?

Branch connections off the main gas supply line in a recreational vehicle should be made outside the vehicle. This placement is essential for safety reasons, as it minimizes the risk of gas leaks and subsequent hazards inside the living space of the vehicle. Making these connections externally allows for better ventilation and reduces the potential accumulation of gas that could pose a danger to the occupants.

Furthermore, if a leak were to occur, it is safer for such connections to be made outside, where there is less risk of gas escaping into the confined interior of the vehicle. The design of recreational vehicles typically considers these safety elements, which is why external connections are the standard practice.

Other options may suggest making connections inside the vehicle or at specific points that do not comply with safety regulations, emphasizing the importance of following established guidelines to ensure the ongoing safety and functionality of the gas system in recreational vehicles.
