I bought a Honda 3000 and had manual switch installed on the panel box in the house. I made a plug that I hook the generator to the house with, turn all the breakers off I won't use and flip the manual switch cutting of Line power and putting me on generator power. It being the 'overpriced' model I don't worry about electronic devices in the house I may choose to use. I can't run the AC obviously but it will power the furnace blower and keep me from freezing and busting pipes in the winter. I don't have to string extension cords around for the fridge and freezer and my wife can have lights in the bathroom and use her hair dryer. Like in your camper you have to manage power but it will get us through a few days. I'd get a bigger generator down the road for my toyhauler the 3000 is enough so I went with it for my dual use power supply.
