Thanks Itsy that is what I thought.
To the O/P they will not fix your problem for that's not where the leak is. If it's leaking it's under the A/C the gasket between A/C and roof. and as others have said. remove the LOWER cover (inside the RV) and check the gasket and the 4 big bolts. Odds are a turn or two all the way around will fix you up. IF NOT then you may be in for some serious work on the roof. This requires REMOVING those same four bolts. then removing the A/C and replacing part or all of the roof.
