Keep your chin up, bearing in mind you have done a lot to sort this you may be nearly there. Some vans have been known to have pinholes in the roof which then follows the easiest route to ground level! Just because the water is showing up in the corners doesn’t necessarily mean that’s where the leak is. Just a thought.
This guy is a friend of mine and has made a lot of videos on damp repairs. Useful viewing on a wet evening
