I have had my honda eu3000 for ten years and it has been flawless. It runs my 15k ac no problem. It also has a 3.5 gallon fuel tank built in. I have it mounted permanently to a cargo rack which I can put on the front or back of my truck or the back of my 5th wheel. I really really like the genny super quiet and super dependable. 20 + hours run time on eco mode. The number one thing is quiet. If it is really quiet you can run it just about anywhere without PO other campers. My first genny was a contractor generator. I used that one exactly once at the campground for just a little bit and realized that was not going to work.
