Trailer Tops

[m151dave]

When I was in the Army, I remember a lot of the M416 trailers had rigid tops made for them. Usually plywood with hasps to lock the lids down.

I was wondering if anybody had any plans for such trailer tops? I would like to make it as water tight as possible.

Ideally would like to make the installation as unobtrusive as possible, meaning not drilling a lot of holes into the trailer body.
