We own 4 jeeps currently, all 2018 and newer along with several others in the past.
We tow a 2018 Wrangler Unlimited Sport.
I have NEVER experienced the "death wobble" and in reality probably 99% of Jeep owners haven't.
I have read that it has happened to other Jeeps models, not just the Wrangler. Im not an expert but I understand that it seems to happen to highly modified jeeps with lots of aftermarket parts involving lift kits and the suspension.
The blue Wrangler below is completely stock except slightly larger tires.
I wouldn't worry about it, especially if your not heavily modifying it.
