Uninteruptible Power Supply as RV Inverter?
So I was looking at some rack mount UPS's on ebay and it looks like you can get some decent deals... About $100 for a 1000 watt Pure Sine rack mount (professional) system with no batteries. What i...

Um, excuse me for raining on your parade, but do be aware that all the UPSs _I_ have ever heard about are Modified Sine Wave, not true sine wave. $100 is way, way, way cheap for a true sine wave inverter in the 1,000 watt range. In spite of the UPS peddler's best efforts to tout their systems as "safe for computers and other sensitive devices," the fact is that computers, being inherently VERY sensitive, have been designed with robust power supplies so that predictable crummy power, like from $100 UPSs, cause no problems.
The power brick for my Macbook Pro says on it "100-240 volt, 50-60 Hz" input, which says to me that it is a switched and regulated power supply, not a transformer power supply, and that as such, it can handle some pretty crummy power.
Now I'm sure that with enough money and an electrical engineer to design it, such a system could be put together. But not for $100.
