Generator info for new trailer
I have the Honda 3000. When first I hooked it up, it died when the AC went on. Then I installed a 'easy start' kit in the AC (big capacitor and a relay, cap charges before it tries to start the compressor) and it works fine now.
This unit is quiet and gas efficient, and easy to start (key start). On the down side, it is heavy and taller than my truck bed, which made finding a cover for it a challange. And now I'm trying to figure out how to deal with the exhaust. If you don't mind schlepping them around and starting/stopping them as needed, 2 EU2000 may work out better. Yamaha has a small generator which might be smaller and cheaper than the EU2000 with comparable noise and effeciancy, but I don't know if you can gang 2 of them like the EU2000 is designed for.
If you plan to mount it in the trailer, probably you will want to look at Onan (or possibly Generac has a built-in model)
