Need Advice re: subfloor

I am currently redoing the sub floor in my 71 Overlander International. Do I use 3/4 inch plywood or is it thicker. Some say 3/4 some 5/8?

Can someone tell me how to repair this? It is the rear U channel - it is broken in two places where it makes the bend on each side.

Next question - Is something missing here? This is where the water heater door was. It looks like someone used a drill to cut the U channel off.

Another Question - I have heard about the fiber optic wire in the rear lights. What is it for and where does it go. Mine is right here LOL

Last question - Any advice on how to repair this area? It is right behind the door for the water heater. This is also the patch that was screwed on by about 30 screws - RTVed and painted silver. LOL

On your first question.

I would get some flat stock and cut a curved piece to drop in the channel and rivet it down. Then cut pieces to rivet to the vertical legs of the channel.

The fiber tubing ran from the tail lights to the front of the trailer at a location you could see in your rear view mirror. They carried a signal forward when the brake lights were on. A nice idea to tell you if you were missing a tail light but not a real necessity.

Short of buying a new rear quarter panel anything you do will look like a patch.

My C-channel just had some cracks that I reinforced and I did exactly what Howie suggested you can see a pic here.

The fiber optics were attached to a small box attached to the street side of the trailer. This would allow the driver to see that the trailer lights were functional while towing.
