I redid my trailer boards a few years back similar to this after the metal brackest started to fail.

I used 4x4 treated fence post boards, but I did not want to drill holes [weaken the channel iron] in the trailer cross braces so I used Hot dipped galv. U-bolts. I bought the U-bolts so that the bolt and nuts would be counter sunk. After the boards were installed, I filled all the holes with grease to further protect the nuts and threads before installing the carpet.
