Big truck passing

I done several searches on the following topic but could not find anything on it. I am usually driving in the right lane on the interstate or a four lane road. When a big truck passes an the left as it gets about even with me our rig is pushed to the right. It's usually just slight but sometimes it be a fairly hard push. It's only scared me once on a US highway. It happened right as I and the truck driver crossed a bridge. After a rather strong push I am estimating the side of our MH was less than a foot from the bridge and it was a bit scary. Some big trucks don't blow our MH at all. I'm not sure what's up with that. Our MH is 28 feet long and 11 feet 7 inches high. I have noticed bridges on US highways can be much more narrow than on interstates.

Mine does the opposite on the interstate. I used to pull a heavier trailer without WDH or sway control so it the push away from the passing truck was felt in the tow vehicle. Now with out new unit and WDH / SWAY I feel the tow vehicle get pulled toward the passing truck. I found that towing at 65 instead of 70 greatly reduced this feeling and at 60 it's barely noticeable.
