Since your generator will not provide the 12,000 watts for a true 50 amp connection, you will an adaptor to change the current 50 amp four pin connector to a 30 amp three pin connector. These are available at various RV outlet stores. Then you will need a 30 amp RV connector to a 30 twist lock connection. The twist lock will go into the generator power outlet, then rest are hooked together to supply power to the RV. Just remember that you can not run both A/C's off that small a generator. One at a time plus whatever other load you are going to have on it. A microwave will take between 800 and 1500 watts by itself. Enjoy.
