Generator rating

I have 1975 Terry 21' trailer and a 1998 Rockwood Ultra light.

How do I figure out the wattage of generator I need for them?

    Does the trailer have a 30 amp service?

    Do you wish to run the microwave and the air conditioner at the same time?


    I am not sure of the amp service. I will find that out when I can get at the trailer.

    I would like to run both, as well as the radio and any other power I might have on.

    Trailer panel is rated in amps. Generators are rated in watts. I want to run everything.
