Winter storage advise?

Lots of great advice....some I have heard, others are new to me. So far, I had already topped off the tank and added stabil so hopefully that will not be an issue, I have her on jack stands, pulled the battery and just bought a battery tender a couple of weeks ago....she is in the garage, but no heat..so moisture is still tbd. ..and sounds like some more work to do to prevent moisture and mice....

Seems like the group maybe split on oil change before or after...curious if anyone feels strongly one way or the other....why?
I heard never leave dirty oil in crankcase. I always put in new oil before storage , better safe than sorry .
