So far it is an excellent purchase for hurricane season, will power entire house, and easy to store gas/propane for extended outage. Plenty of feature for every use so far.
I fired it up on propane and powered some house circuits. It started with no hesitation. The manual is bit un-organized, mixing warnings, setup, and operating instructions. Discovered I need to buy extra parts for operating at high altitude (above Denver) but the parts are not available.
