loose / unstable on bumps at high speed. Is this still going on?

Not once have I been forced to slam my brakes on a slow-moving vehicle to correct it

 Well which is it? Slamming on the brakes to correct a fish tail, a new expert technique from the autobahn cruiser.

any vehicle should not be fishtailing, period... I used to live in Rochester with snow...

Hmmm... I may be from Oklahoma but we've never had fishtail proof snow here.

 

We all better start watching out, without the proper experience and training from

 your truck may also be susceptible to wild uncontrollable fishtailing

Puhleeze... the ditches everywhere must be littered with these trucks. You are literally the one person this happened to... I'll give you some extra just in case the others this happened to don't use the internet - a hundred fair? Out of what millions... including every sort of lousy driver known to drive. Obviously, these trucks are the problem. 

 

No. You lost control of your truck on a washboard road.

I experience a similar issue in my 2022 Silverado LTD Custom...it's definitely butt-hole-puckering the first time it happens, and it's quite unexpected. Been driving pickups all my life and this 2022 is the first one I've driven that has this behavior. So @wiggums is not the "only" person to experience this. I use my Custom as a work truck and it always has anywhere from 200-500 lbs of stuff in the bed at any given time. Happens regardless of loaded or weighted.

 

So maybe the flaming in this thread needs to ease up. Just trying to be constructive.

 

My plan to help is install new Bilstein 5100's on the rear, as soon as financially plausible.

Same experience with my 15 K2**. It started the build thread. What's that Tyson use to say? "Everyone has a plan till I hit em in the mouth". Quite unexpected indeed.

Well you certainly convinced yourself. Now you just need to convince everyone else that has driven both trucks back to back.

 

Not hardly.  A man has got to know his limitations.

Interesting, my previous work truck was a 2016 Regular Cab, 8' bed. And it never behaved anywhere like this. The suspension on my 2022 is definitely really soft compared to my 2016 though. I think a decent set of shocks will definitely resolve most of the squirrlley rear end.

Mine, a standard bed. 119" wheelbase. A regular hobbyhorse.

 But I love it. Wife and I call a RCSB, a "short-short". 

And yes, a good set of shocks took that nasty little trait away.

Threads like these bring back memories for an old guy like me. In this case I remember my father bringing home his first factory performance truck. A 1970 CST Hugger Orange 402, 3 on the tree, posi short bed truck. The first ride was dad, mom, little sister in front. Three boys in the bed. Most of the roads were dirt and not very wide. Usually we pile into the Buick. But this was a special day. We didn’t get too far and the back of the truck started dancing along the washboard road. Enough that he turned around and that was the last time we road in the back of any truck. Once the toolbox and fuel tank went in the problem was solved.

Your speed is a big factor.

The 1000' climb up to the hacienda is winding, curves, snow covered, wash boarded, iced at times since it gets odd sunlight then refreezes. Its always a hop away from going 90o to the road unless you modulate the torque with your throttle.  Sometimes you need the rear to lock sometines its better to allow normal diff action.  Traction Control program is NOT good with this hopping so it get shut off frequently.  The low end ( 1500 rpm mx tq capabilty of my L3B) is awesome for gently working up a dangerous hill.  We have two CAT graders that rework the road complex here every 3-4 days when they aren't moving snow or clearing water vents under the roads. 200 miles of roads the landowners group together to maintain.  Going down that hill can be deadly, we have lost folks who can't drive or too old to care anymore.  Driving too fast will get you the same hop, skip, slide right off one of the turns and you become mountain lion meal.  We are having issues with summer city folk not realizing that a JD swivel bucket or grader road maintainer has blind spots and they are offended when they almost get crushed........ignorance will kill.

You're not kidding. It was the least thing I'd expect from a car on a straight road especially at 35 mph. The ripples got the rear end wildly jiggling so I let off the gas on the dry and straight road with dirt caked on it. A good 10 seconds later, the rear was going off while the front end stayed planted on the road. Maybe I should have gone faster, it was the right frequency of the ripples that sent the rear end off, a very odd experience. Have only experienced it twice, the second time was on the road to the family hacienda. In fact, I drove back and went about 10 mph faster and it didn't get jiggly so I went back on the road at 30 mph and it got jiggly. I am not the only one who experienced that, but definitely the first to mention it and got questioned over my driving experience. So stupid.
