Storage under a car port

[Guest TheBugMan]

With three classic cars, two of them restored show cars, and one a halfway done project, I've decided to make the project a daily. I have a two car garage for the show cars, just put a carport up for the third. 

 

I'm going to be putting some weed barrier down (no slab), but was wondering if I need a plastic vapor shield instead, even through the carport is open and has plenty of ventilation. 

 

Thoughts?

How much snow do you get and what do you want the cover to do?  If you get a lot of snow the sides covered would be good. 

 

Just make sure that the cover is really anchored down well.  A strong gust of wind can cause major damage to lots of things.  Had a friend that thought his was tied down well and it turned out not to be.  A strong wind caused a lot of damage.
