It’s not the gas getting into the RV that I worry about. Propane is heavier than air so it settles to the lowest place. A small leak in an enclosed space can lead to an explosive air/fuel mixture - called bomb. The USAF has one of those and if you ever see one go off, you’d be impressed. OSHA says that all compartments that carry propane must be ventilated at the bottom of the compartment. Excellent reason for that. Chances for a leak - not great. Consequences- catastrophic.
