Knuff,

$$$$ of the AS, $$$$ of the TV is computable.

Family and fellow travelers.....priceless.

It's your responsibility to rationalize and choose with all variables well considered. Your 20' foot'r being a central factor.

...C would also be my choice.

Properly rated tires, quality hitch with WD & friction sway worked very well on our 22' single axle Safari.

With the Classic, the cost of the haha was a small percentage of the total and the safety and confidence benefits while towing were well worth the investment.


Bob

I would vote for C as well.

Is it possible that there will be an agreement on a tow thread? This is going to be a first for all of us, maybe. Count me as a "C". Jim

Is there really another genuine choice to "C"?

But I really need to add .... a trip to Canada is a great way to break in the new WD and Sway Control system .....

.... and I also need to add .....

.... "C" may be an obvious choice ......

..... but the brand name of WD system and Sway Control is another matter entirely .....


Thanks,



Jay

I dunno. The Cayenne diesel can do well over 7000# (not an issue for your 20' trailer with a GVWR of 5000) but the Porsche tongue weight max is 616. Airstream lists your tongue as 635 and most here have commented on how low that number is when compared with actual use.

Moreover, apparently Porsche says no WDH on the Cayenne and claims that's because the suspension is engineered to handle a trailer dropped on the ball.

Last, even if you can get past the trailer and tongue weight issue - what does that leave for passengers, fuel and gear?

Have you talked with your dealer? I can't imagine towing without a WD hitch but if that's what they recommend, "A" might be the right decision. I would definitely recommend a discussion with your Porsche dealer.

Good luck!

The issue with the dealer is that they really do not know and they will basically repeat the manufacturer's recommendations. Although I am tempted to give "A" a try, I think that the safety first is something I should stick to.

I'd love to trek North to Canada, but it is just not going to happen anytime soon.

Perhaps, this is now the point for the obvious question . If I go with option "C", what brand of WD hitch would you recommend? For putting strain on the vehicle/AS with the manufacturer hitch installed, how does Hensley/PP compare with the other friction-based hitches? The stories of hitches braking are scary and I am wondering whether risking a breaking hitch by choosing the wrong setup could be worse than option "A"...

Don't know how many 'pepper' spurts' we have here.......

Might get some helpful info here.

The towing capacity for Cayennes and Touaregs is 7700lbs. The hitch receiver capacity is 10% of that or 770lbs. In Europe, the capacity is rated at 8% or 616lbs, because they do not use WD hitches and entirely different coupler system and the trailers are smaller and lighter. You can tow your 20' trailer in any configuration of A,B,C. However you may find that you will feel more secure and safe with B or C.

You will not need the full capacity of a WD hitch due to the air suspension but with a Hensley, I have found that it is much easier to adjust the distribution of any weight.

While air suspensions may adjust the ride height, they won't of course transfer any weight on the axles.

Yes, but too much weight distribution can affect the air suspension system of a Touareg/Cayenne causing the system to over compensate. It is a true air suspension, there are no shocks or springs, and the car is always compensating for level unlike manual air ride assist found on American vehicles. The point is that the OP is within the weight parameters and if he should decide to use a WD hitch, a HA or PPP have finer adjustments than Reese/Equalizer.

Air suspension raises the rear of the TV. This transfers weight on axles, in a similar way to WDHs, and levels the vehicle.

..... go to the scales, get some tickets and photo's to prove your hypothesis.

I don't believe you have the leverage needed to transfer enough weight to balance the TV & trailer.

Level is good but WD bars provide the pivot point to facilitate the weight transfer necessary.

Will do, but u need to wait till the summer

If you lift the back of the car (via air suspension, WDH bars, or even by hand), the effect is the same. Which method achieves the best result, is a different story though.

So a HA or PP would be easier for fine tuning; on the other hand, Reese/Equalizer is about 1/5 the the prize and would be ok as well. Our TV (rental) for the holiday trip has an equalizer. We took it out a few weeks ago and I likes the simple setup, quick and straight forward. Still 2 months before the Cayenne is supposed to be arriving, so still time for pondering...
