I put one in my Coleman Mach 15 as it's 61 amp surge was causing my Magnum 3000 inverter to complain. I can say it works very well, dropping startup surge down under 30. It also waits a few seconds so the blower starts first then compressor. My Magnum has no issue starting up the AC on battery if I want.
Was easy to install as they have a video showing it being installed in a Coleman. They seem to claim it would allow a Honda 2000 to start a RV AC, I think it might, unfortunately I don't have my Honda 2000 anymore after getting the RV with its own generator, otherwise I could tell you for sure.
