Dealing with bow wave
I'm having issues with the bow wave from passing trucks. I have a Jayco 328RLS towed by a 1991 Chevy Suburban. I'm using a Reese Strait-Line WDH with 1500 pound bars. The front axle is about 100 pound...

I've heard cracking a window helps, but I always forget to try it!
I agree with the speed difference being (some) of the issue.
Window(s) square footage compared to entire tow vehicle AND trailer side square footage would be way to small to have any noticeable reduction to the effect.
Basically what you have is a series of high pressure "waves" being pushed by the vehicles. At the same time the rear of the vehicles has a very low pressure area (IE vacuum).
As the faster vehicle approaches the high pressure wave will affect the rear of the slower vehicle. This "pushes" the rear of the slower vehicle away from the front faster vehicle (if you watch in your mirror you will see the rear of the trailer MOVE away)since the faster vehicle has a BIGGER high pressure wave.
As the faster vehicle pulls beside you the effect is minimized some but as the faster vehicle starts to pass the slower vehicle the front of the slower vehicle is PULLED towards the rear of the faster vehicle since the faster vehicle has a stronger VACUUM behind it.
Equalizing the speeds so there is LESS difference in speeds reduces the overall effects not to mention putting some space between the vehicles also..
Has nothing to do with windows, WD or sway controls..
