[Descant]

Almost everything in the bah room can stay.
We leave cleaning stuff in the kitchen
Food all goes, except spices, cooking oil etc that won't freeze.

Wine will freeze, break the bottle or pop the cork, but hard liquor is usually safe. We take it all, but left a cooler full of bar stuff by mistake one year, and that's what happened. The wine that guests brought "Because it had a unique label" goes into a "Yankee Swap". Sometimes it shows up again in next year's Yankee swap.
Anything you're not sure of, leave in an old cooler or other plastic box and see how it works for you.

Each generation does stuff the previous generation did or didn't do. I think a lot depends on how long a drive it s to the winter home and which place has the best excess storage.
Edit: Batteries for power tools, jump boxes etc should not be allowed to freeze.
