My truck will also be getting the boot outside when my car gets painted in the next couple months.
90+ degree summers and -20 winters here in Minnesota are brutal on cars.
I am gonna set one of these up on the side of the house:
Unicage Car Canopies : JC Whitney: Auto Parts & Accessories
They are about the same price as a car cover, but it's way easier to not have to cover and un-cover the car all the time.
