I haven't had need to use this yet but I have tested it out. It's comparitively quiet to small one I borrowed last year after we lost power for a week due to back to back hurricanes. I am a bit concerned about fuel consumption as it was impossible to get gas for several days the last time but with a few 5 gal cans and several LP tanks I should be fine. My final goal is to eventually tie this into the entire house and I'm sure it will be able to handle my needs.
Already had a 50amp hook up on my house. Put some oil, hooked up the propane first, assembled the wheels, and it worked as a charm. I tested the propane first due to some reviews stating issues with LP. Needless to say, gasoline worked as it should.
