Depending on where you are.... many people are not inside, but out doing/seeing things. That's generally the case with us.
If the weather is nice we will bring meals outside, or sit under the awning, on a non-busy day. But we might be inside taking a nap, too.
We don't cook outside, unless it's marshmallows or hot dogs over a fire.....I hate dragging cooking stuff out and back in. Having an indoor kitchen is one of the prime advantages of a RV.
I'm kind of with you, though..... if I want to stay inside and watch TV, I'll just stay home.
