Take it out !!!!! Take it out !!!!! TAKE IT OUT !!!!!
If you leave it in, it will make your headlights burn out faster !!!!!!!!!!!!
Now, realistically, if you have some place out of the weather to store it, take it out, keep it warm and dry (or cold and dry) <mainly just dry> and lube all the places that rub metal on metal with wheel bearing grease.
If there's any chipped paint or rust, now would be a good time to sand/wire brush the rust and repaint the places where paint is damaged.
Or--- if you don't want to mess with it, you could just leave it in the truck till next spring. (but watch your headlights)
Hmmmmm Mine is in the pole barn, under the bass boat, on a piece of plywood and wrapped in a torn up canvas tarp. LOOK OUT HAMSTERS, GERBILS, or maybe just CHIPMUNKS !!!! LEAVE MY STUFF ALONE !!!!!
Happy Thanksgiving everyone
