Apart from the 'permission granted' gags, what is the root cause of leaks on both sides of the cab?
The ingress point of water in inclement weather is up under the dash, on both sides.
What have i missed here guys? A seam not properly sealed, a vent seal not sealing?
Anyone else had similar problems and how the feck do I solve it?

Yours, with very clean feet.
