Thanks for asking, the generator was transferring over to the RV fine two or three times that we tried/used it. You could literally hear the transfer switch cut over about 10 seconds after turning on the generator. Then all the sudden it wouldn't transfer. The shore power cord does plug into a socket, but we never had to plug the generator in. There looks like a cable comes from the back of the generator and goes up through the compartment and into the RV.
