You will get differing opinions on storage prep.
My Stepfather used to drive the stuff into one of our garages and shut the key off. Period. Never had an issue that I witnessed by doing so. But they usually were driven a bit each year.
I do fill the tank, remove the batteries and starting two years ago I put about 100 dryer sheets under the hood and in the interior.
Three years ago I had a squirrel take up residence between the hood and the hood liner. He didn't chew anything, just stored a gazillion acorns in there. A few rattle out on occasion even now when you open the hood. Nothing worse than losing track of one's nuts. Plus he hates the smell of dryer sheets......
Once I fill it with summer fuel I am committed, can't dig it out mid-winter without having to deal with the fuel.
It sits in storage from November until April, no adverse issues other than the squirrel.
I do change the oil, the oil filter and fuel filter after digging it out in the spring. Check for surprises in the air breather as well.
I don't block up the axles, apply a coat of wax or smear any cosmoline on it. Being in a cold climate makes a difference in what I can get away with for sure.
