I'm towing 10,000 bumper pull Toy Hauler. I'm under my Gross weight in both the truck and Toy Hauler.. My TW is 1440 pounds including the hitch.
My trailer sits level when being towed. But everytime I'm passed by a big rig or a big box truck I get sucked over.
Is there anything I can do to deal with this or is it just then nature of the beast!

I think that the bow wave from the big rig is getting you. Brace yourself.
I've seen them smile when they blow by?

High pressure around the front of the truck (bow wave), and low pressure on the sides of the truck. Bow wave will push you away and the low pressure area will pull you toward the truck. Just the way it is.
The larger your tv is, the less it will affect it.
Just keep your eye on what’s coming behind you so you can deal it. Real fun when you are in a situation where you have a semi on both sides of you at the same time with one passing beside you and the other just starting to pass.

When an 18-wheeler overtakes your RV, it's bow-wave of air hits the left rear of the trailer 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 steering
As the 18-wheeler bow wave moves toward the front , it pushes the front of the trailer to the right, 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 have AIRTABS on my Class C.
They really help on a cross wind situation,no more sudden buffeting. It has stopped the sideways push when being passed or passing a large truck.
They are a vortex generator that produce a counter rotating air trail several feet behind the vehicle, This airflow alteration improves vehicle stability. As far a mileage it may helped some but the stability they provided is amazing.

If possible and you see them coming move over as far as you can safely to increase the gap between you both. I've read opening a window on each side of your trialer helps also but not tired that.

A Hensley or Propride hitch will eliminate the big truck push pull.

Yes my TT always had a very slight rear end sucking sensation toward the Big Bad boys. This occurred both with and without a WDH. I quickly learned to anticipate and not over react with the steering wheel. Just let it ride.![[emoticon]](https://forums.motorhome.com/sharedcontent/cfb/images/smile.gif "smile")

Space, and I don’t mean the last frontier.
Hug the fog line, every extra inch of space between you and the truck makes a huge difference in the bow wave effect.
