My shop is heated so not as much to worry about..throw about an ounce of isopropyl alcohol which helps remove the water from the fuel, fill the tank to the top, drain the carb bowls, pull the batteries for those that have, change the oil and diff oil, cover and store.
Probably won't sit more than a couple months anyway.
