Large seams are sealed with Vulkem sealer.
Small seams are sealed with Par-bond.
Since you have the interior metal off, you should be able to see the inside of the exterior shell.
You can also seal all the seams from the inside with a good quality automotive underseal. You can usually get that underseal in spray cans. The underseal must be a "good" quality."
You did not state the year of your trailer.
If it's older, ball park, than 10 years, check all the exterior gaskets, windows, access compartment doors, entrance door, and the sewer vent pipe cover gaskets. Also check out the ceiling vent cover gaskets.
Is the entrance door fitting correctly, or is it warped?
