Looks like Westinghouse dropped the igen2000 model in 2017. I'm liking the iGen2200 for the increased power. The iGen2500 might be overkill for a 9200 BTU roof top Coleman Mach 8 cub. Yes I agree the Yamaha is better quality but believe it or not the Westinghouse iGen2200 has 2 hours longer run time, you could sleep 12 hrs without refueling.
Is around 4 db quieter and is also lighter by 9 lbs and half the price. As much as I like the new Yamaha 2200 watt model I'm really thinking of going with the Westinghouse at just a little over $500. Yamaha is closer to $1100, big price difference. Westinghouse has some good reviews online and Youtube as well. Also theft, not saying it will get stolen if I chain it up but the Westinghouse is going to be much easier to part with/replaceable if they get away with it. I'll burn up a iGen2200
while I wait for Yamaha to come up on their specs. Looks like the Honda EU2200i is the quietest at 48db but is also expensive and has shorter run time. Those onboard Power Tech and Onan Generators sure are nice but not for the expense! Any other on board permanently mounted RV style options out there I'm missing out on?
