Strange I-70 Question

I've had to drive from Baltimore to St Louis and back 4 different times between Halloween and yesterday and I've noticed something strange on I-70 in Ohio and Indiana. It seems my wheelbase aligns exactly with the peaks and valleys left over from screeding the concrete when the road was built and it causes the truck to bounce or hop regardless of speed- as slow as 50, as fast as 90. My question is, have any of you driven this stretch of road and experienced the same conditions? I really don't think it's a tire/wheel balance issue as it only seem to happen on this road in these states. Oh, my rig is a 2024 Rebel with the 6.4, no mods. Thanks for any replies, and Merry Christmas!
 
I was just down on I70 about a week ago. I was driving a Tahoe though, but didn't feel anything abnormal. I'd say it's definitely got something to do with the wheelbase being just right (or wrong). I have noticed that on different roads though. One time in particular I thought my Jeep had a flat because it was so bad. And that was just a 45 mph asphalt road, I can only imagine how annoying that would be across 2 states at 70 mph.
 
There's a section of I40 around Salisbury NC that is the same way. The waves in the concrete are completely unnoticeable it every other vehicle I drive except my truck.
 
The only thing that I’ve found helps….and I’ve had this with Rams and Fords…is a couple sandbags in the back to get the springs to a place where they’re a little more compliant….
 
Thanks for the replies everyone! Glad I'm not the only one that's experienced this. I definitely think that running empty played alot into it. I'll need to keep about 20 filled sandbags next to the garage so I dont end up having to make the trip empty again lol

Yes, I experienced the exact same problem with my 2021 RAM 2500 Crew Cab on the same stretch of I-70 a few weeks ago with empty bed. I had just bought the truck so was unsure if it was the stiffer suspension or what. Had to slow way down to stay in the seat. I did not notice a particular problem on other roads such as I-71, I-465, or I-69. My wife was in front of me in a car and had no such complaints. So your wheel base theory makes sense. Will try some sandbags.
