I am about to buy a eu7000is generator that has a 120v 240v switch. It has a 4 prong 30 amp plugin that you use an adapter to get the 50 amp plug on my fifth wheel. I have concerns about 240v going to my Big Horn but have read that the electrical box in the RV splits the 240v into two 120 v's and this generator will power both ac's and most everything else. Anyone have one of these Honda eu7000is generators?
