I am installing a backup camera for a 5th wheel and also a plug for the trailer lights & brakes. Can I enlarge the two holes in pic to fit two of these plugs?

I would say no. That area is several layers of steel, where the box and supports come together.

Maybe get a piece of metal plate, drill the holes you need, mount your connector and camera and then mount the plate to the edge of the bed?
