The big tornado of Brown county, only F2: I thought F3 after I have seen Bill Dom's video and the house destroyed....
The house that was damaged, I believe, was shown in Mike Peregrine's video about 2/3 of the way through. I didn't see the damage in Bill Doms video. A still from Mike's website here:

This was a modular home, manufactured in a factory, with the large components put together on site. The quality/sturdiness of modular homes varies, but is often between that of a mobile home and wood frame home.
The other two homes affected (wood frame homes) were not as badly damaged.
