A load shed should shed more than just a single AC unit but of course, we're talking about the RV manufacturing industry where they need to unzip their pants to count past ten.
First order like j-d suggests is to determine if this is a forced disconnect, or if a forced disconnect is possible (equipment there or not installed) then find out what ELSE is connected to the load shed. Usually load shed should be auto recycle meaning it should reset itself automatically. Start hunting and see if anything else may not be working including receptacles (wall sockets).
