I keep a small refrigerator at my out of town property for just that purpose. Holds about 1 case of beverages. I had two fridges, but one of them gave out just the other day.
It's nice to have the beverages handy when working on your truck. Especially during the summer.
But, I agree with cdowns. If you get one, it be wise to spray paint the glass or cover it, otherwise you'll have a lot of buddies come over.
