We plan to travel pulling the camper trailer behind the vehicle and camping some place along the road as we go from one National Park to another. Park Advisor apt on the phone allows us to find a camp site spur of the moment it shows all he camp sites in our area as we travel. But if no last minute camp site can be found we can spend the night in Walmart parking lot with a 5.5Kw generator in the back of the vehicle. Camper trailer is 120 volts AC, lights, water pump, AC unit, microwave oven, electric hot plate, coffee maker is all the electric we have. Some GUY on the camper forum claims it can not be done with a non inverter generator? I never heard of such a thing not sure there really is? RVs are all 120 volts, 15 amp or 20 amps or 30 amps or 50 amps. My 5500 watt generator has 2 outlets that are both 120 volts 20 amps each. The 240 volt outlet is 20 amp. There is no way I can run my RV on any of the generator outlets the RV has a 120v/30a male plug. I need a 240v to 120v step down transformer 5KW to convert 240v/20a to 120v/40a. Maybe this is what the guy is talking about, I never seen a generator that comes with a 30amp 120 volt outlet????
