JKU is stock configuration. I just thought there would be a replacement bumper with a built in receiver that may be stronger in torsion compared to stock. The towing issue at least for a JKU is not wheel base. After all, the liberty is rated for 5000 pounds. The issue as I understand it is regulations in the US because the top does not protect the occupants in a crash. JKU gas powered in other countries is rated for higher towing capacity than the US.
The difference between the Wrangler and the Liberty is what might happen in a panic stop - the front wheels coming off the ground (Wrangler) due to the trailer that limits its towing capacity.

If you read your manual, Jeep/Chrysler recommends the use of a weight distribution setup with heavier loads. I would leave my class IV in place and use a distribution hitch. Just make sure you get one with the proper rating, tongue weight plus cargo stowed behind the rear axle weight, or it won't be pleasant.

Weight: JKU = 4340. Liberty = 3985

So now tell me why the Liberty is rated for 5000 and the JKU is 3500? It is NOT because the wheelbase, width, or weight.
Suspension height and geometry will cause these two to react differently to weight transfer from the trailer

Per the original question. I used to use the stock hitch with a reese weight distribution hitch and the bolts at the cross member were always getting loose due to the bending forces.

I upgraded to a different bumper that has the centerline of the receiver directly in line with the thru bolts that attache the back of the bumper. After this change I no longer have the loosening problems.

So in my opinion the rear connection of the bolted components o the jeep can be improved with a quality after market bumper.

That will happen because of the sway control system

Any idea what bumper you installed?
