Parked for the winter :( Need Advice

[BarnabyHooge]

I've decided that instead of keeping my "rough around the edges" '71 on the salty streets of Chicago over winter, I'll be parking it next to my in-laws garage in the 'burbs. It'll probably sit for from mid Nov. until about March.

Is an expensive outdoor cover really necessary? My only concern is rust since the paint is roughed up anyway. I'm certain snow will still be getting at the bottom with or with out a cover. Can I just tarp the bed?

Thanks!
