Help! Frustrating Roof leak around A/C

I have been on top of my 2004 Airstream Bambi 3 times trying to seal it to keep water out to eliminate this link. I sealed EVERYTHING that had been sealed in the past and then the front and rear seams before the roof curves down. I used EternaBond around the Fantastic Fans and the A/C. And then an entire tube of Dicor around the seams of the EternaBond. I then used more Dicor around everything else like vent pipes and bathroom fan, etc. I have sealed everything...or at least I thought. Well, yesterday I walked out to the Airstream after it rained and sure enough, the leak was still there. It's coming out of the A/C.

What am I missing?!?

Have you checked the bolts that hold the A/C unit in place. Remove the inner panel and you will see 3 or 4 nuts that hold the unit on the roof. If I remember correctly, they should be tightened to 5 ft/lb. I have had to tighten mine a couple of times to stop a leak. Good luck!

Make sure the gasket is intact, and thick enough. Some installs take a stack of two gaskets, and sometimes one gets left out. The roof curve can be a challenge getting a good seal if gasket is not thick enough or not compressed properly
