Yeah, that kind of thing makes me think 'why do they have six refrigerators?' or 'is the electric dryer running literally 24/7?'.
We do need to get down to less freezers but we have some home kill that we need to get through first.
I normally don't stay in places with a dryer and just let things air dry. If you're running heating/ac, they normally lower humidity so things dry really fast anyway.
6 a day is on the high side. It's probably an overestimate.
When there are no new borns we might dry 3 loads a week.
But the house is a work in progress. The curtains blow on a windy day.
