something that bad looks like it could be the aerial mount or the awning rail

As far as possible, given the current state, photograph everything that might be difficult to figure out later, especially how things are orientated to one another.
Also measure positions and sizes of parts, where screw holes, wiring location etc and don't throw anything away until you are certain it is no longer needed for reference

Oh sorry to hear this. If it's any consolation, I have had a leak or ten on my old caravan. And fixing another one right now!
Where the water gains entry on the outside is not necessarily where it's coming in on the inside, it can travel and meander a long way from where it's getting in on the outside, to where it eventually ends up on the inside.
Try examining in minute detail a bit at a time, the seals/sealant along the top and sides of the caravan. A leak on mine was coming right from the back of the caravan, travelling down the inside of the roof, and exiting on the inside below the front window. I found out where the water was getting in by getting a neighbour to stand outside with a hosepipe and wetting a little bit at a time, further and further back, while I waited to see the water coming in. The moment I got the ingress, I asked him to stop running the hosepipe on it and mark the spot. Sure enough, you could see at last where the water was going in, and it was 6ft away from where it was coming out on the inside!
As you have already started the repairs to the inside, just do the above as it's already wet again. Then seal the outside, and dry out the inside and carry on. If you need to dry it out before you can see where the water is coming in, put a tarp over the top.
And good luck.

Just remembered another trick to see where the water is coming in. Get a roll of duct tape. Tape up the seams, rails, trims,etc., where you suspect the water might be coming in. If no water comes in, then you have the likely suspect(s). Peel the tape off a bit at a time and examine the seams/rails/ etc closely for defective sealant, loose screws, etc.

Glad you found out where the water was getting in.
Don't fit the new ply until you've made sure that the interior of the wall is completely dry. Or you will be sealing up damp which will start of rotting again. Spend plenty of time waiting for the area to dry out. I used a small damp meter from Amazon to keep checking, until it read 0%... and that was dried out from 40% damp!
This chap on You Tube had a good idea for preventing water coming in over the windows in his caravan, it maybe could be adapted for your awning rail. Thinking of doing a similar thing above the rail the window hangs from on the front of my caravan.

i fitted those to all the windows on my old 1995 swift last year and its a good thing to do amazing how much water it takes away
Great to have some input from someone who has actually done this! I think I will do the same at some point, it can only help, and shouldn't cost too much.
