2021 Ram 3500 diesel- Loud Humm at 70mph

[Kmo]

I have a rand new 2021 Ram 3500 DRW crewcab, longbox, Laramie diesel, about 2500 miles, and just started to get a loud humming sound after I hit about 70mph. Just noticed this weekend. Went on a trip, not towing, and thought it was one of those small cars with the loud exhaust next to me. It was not, it was my truck, and as soon as I slowed to 65mph the hum goes away. It's amazingly loud and annoying. Seriously bummed as I just spent a small fortune on this truck. Anybody experience the same thing? And hopefully you have a fix?
