I figure that the Honeywell has more output because it is a 2000 watt continues run and 2200 surge, where the honda is 1600 continous run 2000 surge. As for buying another one, lay that honda on its side and let the oil run away from the piston and you will be buying another one also...mine was knocked over in Houston in the middle of the night and seized up.
I am not bad mouthin the Honda a bit, they are a good unit, the only issue i had and it was done at the honda dealers shop, the newer one stalled when my ac unit hit the compressor surge..it did it twice and the dealer sstraight up said my ac unit was too big for that generator....it was an issue with the AC unit, not the honda not being a good unit....
Now if I had the space, you can bet I'd have a honda 3000 and permanently mount it under the floor and use the remote start.
As for mounting, id love to mount it like asj ha, his is a great setup....but i am too lazy to fab up the box and I am not spending $900 to buy one. So I store it strapped to the side wall on top of the lt rear wheel house and chain it to the rear tire when i use it...works fine until I build a new truck....
So if the honda works for your needs, by all means buy it, you won't go wrong. It just didnt work for mine....
