Thanks guys! Yeah, the more I think about it the more I realize that I need more power. If the refrigerator and the well pump cycle at the same time, they will draw about 4000W to start up. I think I'll shoot for 6000W.
Maybe I'll build a 3FE powered one! Yeah, that's it!
I like the propane idea - the cabin has an LP furnace so I already have a 500 gallon tank. Any recommendations on specific propane generators or conversion kits?
