wind noise while driving with truck camper?

[Notfadeaway]

Just curious, what is the gap between cab over and cab that was causing the noise? I have a 2” gap.

My first truck/camper had a little noise. It was F150 supercrew with 4" gap to overhang, and the leading edge of camper was farther back from top of windshield. I used a deflector on it for small vaguely perceived benefit of improved aerodynamics. My current rig is a F250 Supercab. It has a 1.5-2" gap and the leading edge of the camper overhang is 12"-14" behind the top of the windshield. The configuration seems very quiet as the windshield is the deflector. Plus I have M/T tires which helps cover any wind noise...
