A small in size generator to carry along in a class "C"?

I had a 1000w Honda that I had bought in the 70's we used it to power the TV, Lights, and other small draw appliances. It would charge the batteries in our TT in about 8 hours. Very quiet and fuel efficient. I now have a 1500w unknown brand I got at Walmart for a really cheap price a few years ago because the box was damaged badly in transport. I carry it as a spare for battery charging if my Honda 2000i die.
