So should I wait for a Q7 with Air Suspension for towing?

Yes, I'm so glad I got air ride..

The only thing I have to warn about is chocking tires.. I used to tension the jack just a little then chock off the tires, dunno why I did it that way.. was usually when it'd occur to me I needa make sure trailer wont roll off before uncoupling it entirely.. but now I do it the other way.. because the air suspension will drop as soon as you take the trailer load off and instead of putting a lil load on the trailer jack you end up completely uncoupled.

Is there anyway to upgrade the standard suspension?

not with OEM setup, you could aftermarket bags but you'd end up spending much, much more for anything decent.. and it'd still be an unrated hack job

That is what I was finding too.

I saw this article.

Although there are no suspension enhancement options, like part # F4176 or part # TDR1500DQ, that we carry for your 2013 Audi Q7, I do have a solution for you so that your towing setup will be level.

What you will want to use is a Weight Distribution (WD) system. What a WD does is distribute the Tongue Weight (TW) of the trailer evenly among all of the axles of your Q7 and the trailer. This is actually the better way to go even if we had suspension enhancement available for your Q7.

You will want to choose a WD system with a (TW) range that the Total Tongue Weight (TTW) of your towing setup falls in the middle of. To find the TTW of your towing setup you will need to add the TW of your fully loaded and ready-to-go trailer along with the weight of any cargo behind the rear axle of your tow vehicle. Keep in mind that a properly loaded trailer will have a TW that is 10-15% of the loaded weight of your trailer.

I was noticing my boat pulls better with it full of gas. I am wondering if that puts more of the weight towards the rear of the trailer and lightens the tongue weight slightly.

Bought a 2007 Audi Q7 4.2L with Towing package. It doesn't have air suspension, but after looking at a half dozen of them I pulled the trigger because it was in the best shape and wife approved. I plan to get a load balance hitch today for it.

FYI the manual says no weight distribution hitches

I saw that in another thread. It looks like some people have done it with some success. I am curious to go pull the boat and see how it feels with a normal hitch.

So will you buy another Jeep if they give it a Diesel and better tow rating?

It'll probably be fine, WD hitches are for going over tounge, if u have a 700# tounge rating a WD hitch can raise it to 10k.. most trucks with factory tow give two ratings for tounge.. one with and without WD..

On Q7 however, it's 660# regardless of WD or not.. it's just going to reduce sag instead of increasing capacity.

Never gonna own another christler.. tho I do intend on making my old Jeep a German diesel.. best of both worlds.

I have a feeling they do that due to how the hitch is bolted to the back of the unibody. The bolts are in the horizontal plane along the longitudinal axis of the car. How Audi did it puts a lot of force on the face of the threads themselves, which is what pulls threads out (there is only about 5/8" of threads x 4 connections from what I remember of installing my factory hitch on the 3.6L). Most good class IV hitches (10k lbs) are welded on, class III hitches (5k lbs) are bolted on, with bolts in single or double shear (horizontal plane along the transverse axis of the car).
