After foolishly welding not one, but TWO inverters in my van, I decided I needed to get a little smarter. This thing is perfect. You'll have to do some jumpers between the output terminals, but the end result is you just can't fry ANYTHING. The cool thing is that since you can connect both the inverter and shore power at the same time, you can make the switch between the two fast enough that you don't lose all your clocks and 110V settings, not even my AC unit care.
