I, too, have a boliy generator with an electric start. It powers my 13,500 btu A/C with ease. At 78 lbs, it's also easy on the back. However, word of caution in that I purchased the platinum warranty which guarantees free shipping back to servicing center should anything go wrong.
Well, I had a few problems over the last year and a half requiring servicing and parts. The Boliy Guy was all about shipping me parts and telling me how to fix it. However, he refused to pay for shipping the generator back for servicing. Fortunately, I'm a hands on kind of guy I was able to fix the problems. My Boliy has been reliable ever since.
Knowing what I know now, however, I would go with either twin yamaha or honda 2000 watt generators for the following reasons:
1. Each generator weighs approximately 48 pounds making each easy to move.
2. They are quiet. However, you will pay for this feature.
3. You can run both generators in parallel giving you basically 4000 wats of power.
Trailer life magazine conducted a favorable review of two 2000 watt yamaha's connected in parallel commenting on how quiet they were and how they ran both the ac and microwave oven at the same time.
