About two years ago, I decided to upgrade from an RV oven/stove. I didn't have a need for anything fancy, just a range that would be operable on propane. I was at an appliance place and looked at the scratch and dent dept. I found one a little above my budget, but it was a good match for my fridge/freezer. It did have an AC cord, and I figured it to be nothing more than power for the clock, timer, and elec ignition, seeing as this thing had no pilot light. The unit is a GE Adora. I was ok with using a lighter to light the stove, and had no need for the clock and all. Then I went to use the nice full sized oven. It wouldn't work without AC. So I fired up my 2800 watt generator, and plugged it in. I'm not sure what the designers came up with, but every time the oven comes on, it throws the generator into full power mode. I'm saying, it really puts a load on it. It makes me think that the oven not only operates on propane, but uses electricity for heat as well. There are a number of options on the stovetop configuration, including a removable griddle that can be changed out with burner grates. The four separate burners are various sized, with one huge one called a power boil, and it does that very well. It will bring a pot of water to boil faster than any stove I've ever seen. But the AC/gas oven is a real deal breaker. This is a stupid oven for off grid living. Don't make this mistake.
