Abstract: A recreational vehicle safety system includes two independently operable automatic shutoff valve assemblies. One valve assembly is attached directly to the recreational vehicle's appliance high-pressure fuel tank in such a manner as to be operable in all conceivable crash situations, and the other is connected downstream from the appliance fuel line's high-pressure regulator and is designed to close off the fuel flow when a fuel line breaks or small gas leaks are present, such as when an appliance pilot light goes out. Provided also with these valve assemblies are a gas sensor and warning light and audible alarms located about the recreational vehicle to alert campers to potentially dangerous malfunctions. Electrical and manual resets are provided for the safety system, so that the recreational vehicle's appliances can be made operable again if a malfunction occurs in the wilderness, remote from needed tools and expert mechanical assistance.
