We often camp in the desert where it's cold at night and hot during the day.
I was raised in an unheated room in Michigan with winter snow sometimes on the inside of the window sill next to my bed. I left that stuff at age 19, never looked back, and vowed never again. We also don't care to sit in an RV super heated by the sun to 95+ degrees to eat lunch in the desert when out there hunting for rocks.
We keep our RV's furnace set to 65 degrees at night, and love our RV's built-in generator and the backup portable generator we carry along. Why have a self-contained RV that is only self-contained under a narrow set of conditions?
To us, the sound of a generator is the sound of complete and extreme independence.
