I call it the "suck 'n push", because that's what happens. Think about the physics involved.
When a vehicle makes a wake through the air (yes it's air, but shooters know it's just really thin water) it first contacts the section of trailer behind the axles which pushes away and levers the front toward the passing truck, which has the effect of pushing the tow vehicle over to the center line as well.
As the bow wake nears the trailer axles, it evens out because the force is at the fulcrum (pivot point). Then, as the wake impacts the front of the trailer ahead of the axles, (which is usually a larger surface area) it pushes the front of the trailer away from the passing truck, taking the tow vehicle with it towards the berm. First it sucks, then it pushes.
It doesn't concern me much anymore. I have to only correct the wheel about 1/2" to compensate. Just that the wake is much stronger and sharper with small box trucks and the like.
HUH? You lost me at wake. Too techy for me. There is a lot going on though. :S
