Wiggle behind car carrier

On this trip, we got some minor wiggle when we were behind 2 different car carriers on 95S in Georgia. I’ve never felt this before. Didn’t see it in the mirrors. 65 mph or less. Felt it in my butt. Just a jiggle that quit when I got around one of them. The other was when one passed me and pulled over fairly close. I slowed and increased the distance and it went away.
I am just curious if anyone else has noticed maybe a different air disturbance behind a car carrier.

Car carriers do disturb the air differently. However, if you were south of Exit 29 in GA in the right or middle lane, then that was probably your problem. Those two lanes are uneven enough that they would cause our Motorhome to wander without truck traffic. When we still owned our Hybrid TT I pulled off the road to check the anti-sway bars because the HTT was swaying enough that I figured something must be wrong. We had an Equal-i-zer brand WDH system.

Everything was fine. There was little traffic so I tested each lane. When I got in the left lane, no more wiggle. It's just the middle and right lane from exit 29 south to the Florida line. We live off exit 29 and I see travel trailers wiggle a good bit when traveling south. It happened every time we traveled south from home whether towing the HTT or driving the Motorhome.
