May I suggest to do this step before you return it to the dealer. Recreate the driving condition needed to effect your door noise issue. While in motion, place your fingers in along the interior door seam where you suspect the movement is occurring. Draw a diagram of the interior doorside, and mark on it, the areas along the seam, that you determine is making the wind noise. Present that diagram to the dealer when you drop it off.
From what I observed on my older Solera, there is no adjustment on the hinge side, but only on the latch side. If your door is not in plane with the manufactured opening in the coach body, and the latch adjustment may not fix the issue, there is only one other "fix". change out ( thicker) and or adjust the door rubber seal, to stop the air intrusion during flight.
Dealers are a funny bunch. Some will shoot it to straight, others will give you the BS with a smile. Your issue will best be addressed, if you come to them with your analysis on what is occuring during flight. Then, you will observe the type of dealer you bought from. Good luck and let us know how it goes. FR does a good job. The dealer network can get tricky, especially with all the variables they face, skill set of their employees, while dealing with multiple lines carried on their lots.
I had a dometic fridge failure within the 2 yr mfg warranty period, and interviewed three area dealers who were dometic approved to have it repaired. My expierence with the young lady service manager was spot on. I asked her point blank while she pulled up a schmatic of the fridge guts, how exactly will they fix that, being it is intergrated into the body, she replied "I have no idea", but our service department has certified techs that do. I mean you talk about honest. So, as she stated it was done right, and on time. I just had a feeling. Good luck!
