Friend of mine north of Jackson has a Built in Natural Gas generator. It automatically starts when power goes off and shuts off when power comes back on. He don't touch anything. It starts up and runs to exercise once a month automatically also. Powers whole house including the well and I think he had about 5k invested including installation.
I use a 16 year old 8hp HONDA 5000 watt unit with a manual transfer switch and it powers most of what I need but am selective on what breakers I turn on. I have city water so don't need to worry about water pump but I do have a 220v going to a sewer grinder tank pump and central AC. I leave the grinder off and only selectively turn on when needed.
The RV generator would work fine and I have a friend in OH that uses his motorhome generator to power the house when needed. Just need a transfer switch wired in the house and maybe a plug in the RV with proper gauge wire to connect. Randu
