I think the guys here said what I was going to say. Here in So. Cal we don't have to worry about winter, but when I put my boat away for our so called winters, I top off the gas tanks and and a fuel stabilizer, squirt oil down the spark plug holes and crank the motor over a couple times, put a battery tender on, and jack up the trailer to take the weight off the trailer tires, and for my camping trailer, I crank the stabilizer jacks down to take weight off the tires as well.
