Teardrops n Tiny Travel Trailers

I am getting ready to skin and I am looking for aluminum suppliers in Wisconsin if anyone knows a good source. I am looking for .032 or .040

Thanks for any help you can give me!!!

If your near Minneapolis, Garelick Steel that has .040 white, red, and black, on both sides. Look at the fish house specials. It's the soft stuff, but still looks good.
