It's strengthening the factory hitch assembly's welds only - not your entire Porsche Cayenne.
As I understand it - the Cayenne/Taureg/Audi Q7 hitches need the welds reinforced, as do those on the BMW X5 & Mercedes ML & GL hitches - mainly because they don't use weight distributing hitches in Europe, so they didn't design them to withstand that WD force.
Of course Andy T. from CanAm posting above can explain it better, plus he says some GM hitches were not up to snuff either - so the folks with the Big 3 full size trucks have some concerns as well.
I agree, the numbers thrown around can be confusing & overwhelming, but it's good to go thru it all. Since Andy & others have in fact towed 27-30' Airstreams & other similar size/weight trailers with Cayennes, I suspect that you'll be just fine with yours too.
If it were me - I'd get your Cayenne's hitch reinforced at CanAm to be safe - especially with your being so close - at least relative to me way off in SoCal!
PS - This is the same Tom from the janabanana48 posts above - I just opened my own account so I get the notice emails to my account, instead of my wife's email.
