When an 18-wheeler overtakes your RV, the bow-wave hits the left rear of the coach first, and that pushes the rear toward the shoulder. When the body rear moves right slightly before the rear axle does, it amplifies the push to the left that you feel in the front causing you to correct by steering to the right.
As the 18-wheeler bow wave moves toward the front of the coach, it pushes the front of the coach to the right, and when the body moves right slightly before the front axle does, it amplifies the steering correction you have already done causing you to have to correct to the left. This whole thing, if you are not used to the feelings, can be quite scary.
One way to overcome that is to install Vortex Generators like Air Tabs
They cut down on the dead air and drag on the rear of RV and greatly reduce the bow wave of passing trucks.
I installed them on my Class C and now I do not get any push from passing trucks and it greatly helped in cross winds,hardly a bobble.
