Thought I would add that I did a short review of this generator earlier this year. I've used it for probably around 20 hours and have been very happy with it. In my overview, I did some brief sound testing, and this generator is most certainly not 64db at idle. It's not as quiet as a Honda 2000w, but it offers more power than one. It is also MUCH quieter than a Champion 4000w open-frame that a neighbor had at a campsite in Colorado. No scientific evidence for that one, but I couldn't even hear my generator over his standing five feet away when his generator was at least 25 feet away. Take that for what it's worth, and your experience may vary. It does run the factory 13.5k BTU A/C in my 2009 Mini Lite 1809, but only just. I would recommend a hard start capacitor if you're planning on running an A/C frequently.

Predator 2500w Inverter Generator Report
P.S. The 2500w Predator generator, which is the item I have, has indeed been discontinued by Harbor Freight and replaced by a parallel-capable 2000w peak/1600 continuous generator. I have no opinion on the 2000w model, as I have not used one.
