Sometimes small systems are plenty

My Vizio doesn't have a brick so I can't test that. Although given what Almot said, it probably wouldn't be that much better. Wasn't concerned with picture quality at all. I specifically looked for a TV with low draw. It was to replace the cheap crappy one that came with my "old" 5er. That TV drew a whopping 75W and it was also a 26" LCD. About my inverter, I never tested this myself so take it for what it's worth but efficiency is rated at 80-90%. In reality it's probably similar to that Powerstream converter. BTW, looked at those converters when I was considering going 24 or 48V. Was interested in a unit that could be run 24/7 without crapping out. Some DC-DC converters looked like they could only be run occasionally. The Powerstream's seem to be pretty beefy units. I find the inverter usage to be very convenient and less costly than running from 12V plugs. I have one 12V plug behind the passengers seat in my rig and it most likely is the too small wiring, not enough amps capacity type. Didn't feel a need to run thicker wires and higher capacity plugs all over the place. One inverter and three cables was all I needed for installation. And it's all neatly tucked out of sight. DW and I can plug into any outlet in the coach and get power. No need to run around telling people which outlets they can and can't use (this detracts from my camping enjoyment).
