I have the Champion 3100 Inverter generator and it will run the 13500 btu AC unit on my TT. They are $999 at Costco now and when I got mine almost 3 yrs ago when they first came out, it was $699. For the money, they can't be beat, they are lighter than the Honda 3000 so it is easier to load in my truck. I had the contractor grade Champion 3500 and it was way too noisy for camping, I sold it. I also have a Champion 2000 watt inverter generator that I use most of the time since my need is mostly to keep the battery topped up. I went to the Early RV show and was thinking of buying the 120 watt portable solar charging unit but after I was talked to the salesman, he told me that it needs direct sunlight to work effectively. Most of the sites that I camp at are shady so that pretty much nixed that idea.
