I had a Honda EU2000 and mine wasn't trouble free. But it was all my fault. I let it sit for a year with gas in it without running it and the repair bill was about $180. So make sure you don't do that.
I actually think the combo of two of these is the best thing since sliced bread. You only need both running to power your air conditioners and in most of my camping I don't use the AC's. So 90% of my generator time would just be running one at a time. My current DP has a 7500 kw Diesel genset, and most of the time I'm using it all it's needed for is to charge the batteries. I have a 2000 watt inverter that runs everything but the AC's so all I need is battery power most of the time. It's a huge waste to run a 7500kw generator just to charge batteries.
