Northstar PTO generator, bought originally from Northern Tool. 13,000 Watt, connected to a trailer. it doesn't have an hour meter, but best guess is around 20 hours on it. only used on the house when power was out for more than 6 hours or so. always stored under cover, i put a cover over the gen in case it was needed in bad weather, but never was.
Northern tool still sells these for over $1800 without a trailer. their website has all the specs on it.
asking $1000. Built the trailer big enough to handle a compressor or welder for working off site.
