Hey Tim,
I have a Yamaha EF 1000 iS generator. Use it to run and charge my battery in an overhead camper. Does a great job on camping and fishing trips. Light weight at 28 pounds. Will run about 12 hours on a tank full which is only .66 gal. Super quiet. The thing will run anything but the AC in the camper. I use a single deep cycle in the camper and am connected to the starting battery in the truck. Charges the camera, cell phone and run a laptop like a charm. It will get a good work out this August fishing Wyoming, Montana, Utah and where ever we park for two weeks!
