If you want dependability, get a Honda 2200 inverter and if you want to run your AC, pair 2 of them together. They weigh less than 50 pounds and are very reliable.
A 2000w will run most RV a/c's except for the startup. A while back we had a thread on Softstarts but I couldn't find it. It's a device that spreads out the startup power requirements and allows the a/c to start with a much lower power input. I don't know how they work but they're supposed to reduce the stress on the motors and make them last longer. An a/c requires more than double the running watts to start. A 15k btu will run on 1500 watts but takes over 3000 to start. The Softstart is supposed to get it started with only the running watts.
I read that there are 2 main brands: Softstart and Easystart. They both cost about the same, around $300, but the Easystart is considerably harder to install and program.
