I agree with all those recommended going w/ factory hitch. For all the reasons they mention. I bought the factory hitch package from my local Porsche dealer. It was a competitive price with aftermarket sellers with one huge difference. No shipping charges via my local dealer. Other sellers wanted $100-300 for shipping. My dealer got it from the nearest Porsche warehouse in just two days. My dealer charged me 5 hours labor. I had them take photos to document the installation. It was a lot of work. They had two techs on it for much of the time. I checked and they've done quite a few of these hitch installations. They know how to remove the rear bumper and trim panels. Although I do work on my Porsches myself, never having removed body panels would scare me. I spent just under two grand for the parts and labor and was very heppy with the results. Some in this thread thought the factory setup was too expensive but in my opinion I didn't buy this Cayenne GTS to pinch pennies. I've been towing a 4500 lb travel trailer with the rig for several years and with an Anderson load equalizing hitch, it tows like a dream. I'm glad I went factory.
