Put a sprinkler on top and climb in with a flashlite and marker pen!

Also, take a ride back there down a rough road, you'd be surprised at
what's going on and what needs adjusting. Don't do this unless you
have a good relationship with the wife. After test-drivinging one
trailer, it took a good 15 minutes of begging and pleading before the
trailer lid was opened again!
Cheers,

What is the best way to seal it up and prevent any leaks from coming
through the flat metal roof?
