Hello brand new to the forum. I need advice on how to power my RV. I will be running a 27" tv, small water heater, few lights, microwave, hot plate, lap top, small convection/toaster oven, heater, and Ac. I will mostly be in parks and friends back yards getting power from them. I dont know whether i need 110, 220, both, or something else. Any help would be greatly appreciated!! Thanks alot Joe!
