I added an exterior 4 breaker panel and connected it into the meter base rather than the 30 amp outlet. The big issue I see with running all this stuff off the trailer is that it all comes through the converter and the fan will be running constantly. I am sure that this would shorten the life of the converter as well. I am a big proponent of running outside stuff off a separate receptacle off the main connection rather than through the trailer.
