If it's out of the truck, and you're only going to leave it for a few months, Just plug the holes, stuff some rags in the exhaust, and leave it. I've never seen an engine suffer from a few months of neglect. I would assume carb is dry since you haven't fired it yet. If not, you should empty the carb. Otherwise it won't hurt it to sit for a few months. If you have it out of the truck, it won't have water in it, so it won't hurt to freeze it. As long as you're not leaving it out in the rain, you shouldn't have any issues. If you are leaving it out in the rain, put a cover over it, tie the cover tight around the motor, and call it a day.
