A/C seal leak---------------
Tomenka, Maybe your A/C is leaking through the A/C seal? remove the bottom of the A/C (trimplate) by removing four screws. Once it is removed look up inside the bottom of the A/C, you will see four (4) large screws or bolts. One in each corner (should have a yellow tag on each).
These bolts hold the A/C on the roof by compression against a roof seal.
These four (4) bolts or screws because of age has worked loose. Simple
give each one a one turn to re-tighten the A/C against the roof seal.
Sometimes 1/2 turn will do the trick. It is by feel (as you know from your trade). This could be the problem of water getting into the overhead.
As mentioned in a early post. "SELF LEVELING SEAL" from a "CAMPING WORLD" or any RV store is a good source for your material needed.
Good luck on the "RAIN FOREST" on your RV.
Maybe we will meet at the Rally in Goshen, IN.
