Stainless steel skin

I was at the metal recycling place the other day, and they have 5x10 sheets of Stainless Steel in the scrap area for $1.00 a pound, I had them weigh a sheet for me and it came out almost exactly 60lbs. So $60.00 per sheet +/-... I don't know what grade it is, but by playing with a weight calculator, I think that it is probably .03 or 22gauge. This seems to be an amazing deal. I priced out NEW aluminum, 5x10 sheets and came up with about $160.00 per sheet.
I realize that SS will be over twice as heavy as the Aluminum, but I have been afraid I would have to give any metal skin a pass because of the price. I am towing with a Mazda B4000 (Ford Ranger) so I am not overly concerned with the weight.
what are the pros and cons of SS vs Aluminum? Like I said, I understand the weight difference, has anyone had either good or bad experiences with either SS or Aluminum skins(mostly SS)?
