Sometimes small systems are plenty
Friday my wife suddenly got the urge to camp. Immediately. All the TT has is the original Group 24 battery, 5w solar to maintain it and a 700w/1500w inverter I've never even run under significant l...

Here's the actual DC-to-DC upconverter brick I would use with my LG 26 inch 720P HD TV so as to operate it directly from a 12 volt receptacle in my RV to eliminate use of the stock brick plus inverter - note that it's efficiency is listed as 88%:

By the way 88% efficiency is higher than most inverters, so in my case I'd use up less RV battery capacity to power my 26 inch TV from a 12 volt receptacle using the upconverter in the link above instead of using the brick that came with the TV and my existing inverter.
I'm not advocating elimination of use of inverters in RVs (so as to directly use 12 volt receptacles) for ultra low current-draw periodic appliance recharging applications such as iPhones, iPads, toothbrushs, shavers, etc. - just use direct 12 volts for as much as possible inside the RV otherwise. For instance, laptops and TVs are often used many hours when camping so - since modern laptops, LED TV's, etc., already use low voltage DC circuitry internally - why not take advantage of this to stop using inverters with them?
I use a DC-to-DC upconverter brick plugged into a 12 receptacle for my laptop all the time and for many hours in the RV ... so it would be very easy to do it with an LED TV, too.
