I switched both our TVs to Samsung 12 volt TVs, bought SONY Blu-Ray players that run off 12 volts for each, got a nice JVC stereo that runs off 12 volts, and got 12 volt power cords for our computers. No inverters needed any more. Much more efficient.
Only things left that run on 110 volts are the microwave, AC, and a 6 gallon 150 PSI compressor I bolted into the rear storage compartment. Just fire up the generator for those if I need even them at all.
