i would have preffered to use thicker aluminum, but this was free. i would have preferred 1/4" treat plate. but that stuff is outrageous. i could buy a new trailer, the one i want, for the cost of a sheet of 1/4" aluminum tread plate, enough to do the trailer.
1/16" would be .0625 which is close to 16 gauge steel. It may be .060 which is one of the stock thicknesses in sheet aluminum. If you have mid supports you probably could drop down to .040 and still be okay. FWIW I work with a variety of metals and it can get very confusing.
