LMAO!! 😂😂 Especially if it don’t fit...

 

That wiggle you feel just might be some sway induced by an improperly set up WDH, low psi in the tires could do that but I had more of a "pogo" effect until I increased the psi in my truck tires.

 

Well if Super Duties can have the Death Wobble, maybe little brother has the Death Wiggle !??

It also can be that you did not have adequate tongue weight and the next time you connected the weight distributed in the trailer had changed.
We may never know the specifics, but fun thread. Heck, he might need to adjust the thingamajig by the kanooter valve.

 

Since it hasn't been mentioned, disable sway control in the menu. In just a few instances, owners found TSC was fighting their WDH.

 

Wondered if that could be the case but it occurred with two different trailers of different size and weight (significant difference). Back out this weekend and we’re loaded much lighter and the feeling is still the same.

All things being equal, the only change was the sticker and completing the setup. We’ll likely never know but it’s wiggle free for now! LOL!

Anyway, keep having fun!
