Porsche as a tow vehicle? Depends on the trailer . . .

"the trailer was a 2019 Heartland Wilderness. The smallest of these is the M-2375BH at 28’ 9”, weighing in at 5,644 pounds with a hitch weight of 690 pounds dry. These numbers are within spec for the Cayenne depending on how the tow vehicle itself was loaded and how the trailer was loaded."

So he assumed the wrecked trailer actually was the smallest Wilderness model, took the trailer manufacturer's word about its weight, and then assumed that it wasn't loaded beyond the Porsche's rated capacity...

I agree, the GVWR of that model is 6900lbs. if it and the Porsche were both loaded it was likely over its rating. Sometimes the tail wags the dog.
