Belfert, I have a couple of reasons for high efficiency. One is that I can only count on about 1800 watts from my inverter while driving, Another is to run as much AC on limited shore cord sizes. It's real easy to find a 15 amp hook up when I'm visiting a relatiive or friend. RegardsJerry 4107 1120
I am wondering how you would run a 220 unit on a 15amp 110 hook upMelbo
