Just food for thought. I owned 2 EU2000 Hondas that I bought used in parallel. Used them for 8 years and found out through Honda that they were 2006 models. I just sold them to a person who needed them both for the parallel capacity on a food truck. After 8 years of ownership - sold them for $100 less than what I bought them for. Fresh oil and a few spark plugs and air filters during my ownership. Well worth the cost.
Look for used as they are everywhere - but they usually go fast. I now have 2 Champion 3500 inverter remote start that are used in parallel. They are twice as heavy but managable for me using them twice a year.
