Plates look great and are easy to install. Only problem is that you can see dent mark and very small paint issues that are hardly noticeable unless you inspect it carefully. Installation video on mustangjackson67.

A bit of caulk around the square and install with screws and your set. It's nice that the female plug is very tight. It creates a waterproof seal, and i didn't have to drill or cut the aluminum siding on the trailer.
