Any car can "tow" on a dead pull what it is rated for.
What many can NOT do is handle the tow in REAL towing situations on a highway. I.E. semi's sucking you in when they pass, windy conditions etc.
It's a case of the ""tail wagging the dog"" with a vehicle with a short wheelbase maxed at rated weight.
I full time and see it all the time. I stay back 10 car lengths when I see them on the road.
To the OP or anyone that feels it's ok to tow right at or more than rated and with a TV that has a short wheelbase go ahead and get back to us after trying to drive your family on a camping trip and fighting the sway all the way every time the weather changes and every time a semi passes!
It is "THE" reason I retired my Tahoe after only one trip with a brand new TT weighing in at far less than what it was rated for! :W
