high-speed buzz in the dash/windshield
Couple other smaller / cosmetic / normal things to take care of but this is the mystery I'm wrestling with now...

She's got an odd buzz at high speeds, seems to come from the top of the dash, back where the windshield vents are... Removing the vents doesn't affect it, and I haven't been able to feel what is making the buzz while it's happening... It's loud enough to drown out some pretty loud music!

Hoping to start towing smaller campers with her soon, anything to watch out for? (I've towed a couple things with an '87 pickup I used to have, but not with trailer brakes...)

The buzz could be the plastic cowling at the windshield base. There are a few threads in the WK2 model technical subform.

Thanks @ColdCase ! Was at the dealership last week and mentioned it to their mechanic and he thought the same thing, replaced the wipers and snapped the cowling down a little bit, and the buzz is better-but-not-gone... Good enough for now.
