Here's a vote for the Honda 3000. Yes, it weight
147 lbs. We put it in the back of the truck with a come-a-long screwed to the ceiling of the shop. Unless, of course, there is another person around and we can con him/her into a little help.
I would be very concerned about using a 2000. The reason is the amount of restart amperage needed to recycle the compresser during the normal cycling on - off that occurs in use. I could be mistaken, but I think that it is just a little more than the normal start amperage, and the initial start amperage is more than double the run amperage.
Bottom line is we can run the microwave
and the airconditioner at the same time in our 17' Casita
