I don't know where 20 amps came from, or at least the thought that that would be my use all day long. I can envision 10 amps, say for the microwave being on for a few minutes. It is a newer rig with bigger fridge, TV etc. I do enjoy my baseball and hockey. Not to mention the wife and her "housewives" while I am fishing. Additionally, using a lap top or the crock pot/fridge while I get to where I am going.
Every light I have is LED (did it my self) and brighter that the incandescent ever was. AND, at 1/4 the cost of the LED's found in stores. Learned a lot (and make a few bucks selling a few).
I am not one to listen to a generator.... anyone's. The ability for free power is a benefit.
I went with a Go Power 2000 watt. Some of the reviews were favorable and from what I have learned here. Hope it arrives this next week so I can have a project next weekend.
