Cool Towing with 2017 Audi Q7 tongue weight

Hi Airstream Fans,

Need some advice on towing tongue weight. The Audi Q7 2017
has a Tongue weight max of 770 Lbs. The Flying Cloud RB25 has a tongue weight
of 837 Lbs. Is the only thing I have to do is Move about 80 Lbs. to the rear
of the trailer. I was thinking moving the Spare thats 20Lbs and maybe the
batteries. That would certainly be at least 80 LBS.

As a novice just want to make sure I'm thinking right.

Not an expert here but was exactly where you are at. Also had a Q7 when we happened upon our 25ft 750TW AS. Yes, it connects and daily driver stylish, hoped it all works, cause thatís what we already have /had. If youíre on flat easy driving...less of an issue. Hills, mountains, downhills, you may feel some concerns. In weeks, due to towing sustainabiltity Sold the much loved 1500 suburban, sold the Audi Q7 all for a better rated vehicle. (2014 GMC Sierra 1500, 5.3, 9600 Tow cap.). Even after yanking the 5300/6300 (wet) trailer on trips, wondered if we have enough....

Many opinions here but itís your safety overall

First, there is a lot of info on how to tune the lashup for a German SUV. Do the research and figure this out for yourself. If you do not have the capability to do that, buy a Tow Vehicle with the capacities that cover your coach and payload when loaded out for travel.

The 25 mentioned above is an older coach. They weigh less. Your late model is likely close to 1000#s on the tongue. Switz did a lot of tuning to get a 25 in trim to tow with his Merc. Was not happy with the result and ended up with a big truck and a 30 when all was said and done.

Good luck with your investigation. Pat

Use a weight distributing hitch. With proper set/up you can relocate about 30% of the tongue weight to the front tv axle and the trailer axles. Your challenge will be payload. Everybody/everything, including tongue weight all count towards your payload limit.

Silver - Whatever you do make sure you weigh your tongue weight afterwards. It's non linear , I.e. Moving 80 lbs to the back doesn't translate into reduced tongue weight. I would not pull that trailer with a q7 personally (I had a 23 FB and a q7 and never would have felt comfortable towing it with the q7 for a bunch of reasons.

Itís not about the ability of the Q7 to pull the trailer.
Itís about the ability to stop and resist the pull of an 18wheeler rushing by on a windy day.
To say nothing about what you do on an 8 degree hill when forced to slow down or even stop due to an accident ahead of you.

Iíll chime in with this... Insurance companies/lawyers have become quite savvy. Any Exceedance of limitations will void your coverage.

The new mega truck campers and fifth wheel toy haulers are the biggest culprits. But your situation could easily be problematic.

As mentioned above, look at your sticker in the driver door jam. You payload includes the tongue weight.

TR makes a point - Never use the teeter totter method to reduce tongue weight on any rig. Move weight to the center over the axles. Move weight lower in the coach. Leave heavier items at home. Use a lighter version when possible. Run with less fresh water and empty waste tanks. Run slower and smoother. Pat

And that my friend, is why many of us have chosen pickups; payload and stability towing a 25' or longer AS makes the trip a whole lot less stressful. Unless you enjoy a challenge, and want to spend a bunch of money making your Q7 a TV, get yourself a better suited TV. Think about a generator, a bbq grill, firewood, gas can, lounge chairs, etc...do you want that stuff inside your TV? I went thru 2 new Tahoe's before I moved to my first PU; and F150 EB which did a great job pulling our last 2 25's AS's. World of difference, great to drive with or without the AS attached. Now we have the F250 with our 28', and it is much better suited for pulling, braking, and payload for this size AS.

There is a whole thread going on this Forum with different foreign SUV's contributing. Believe me, they are very proud and brave bunch of folks! if your so inclined, you should connect with them for sure, including Andy of CanAm who helps many with advise and service to get you set up properly...it's all just time and money. (just remember payload and the "other" gear you likely will want to bring along!)

It's marginal.

Some have made it work with custom hitch reinforcements (Can-am RV). The stock hitch is not really built for this type of load, along with the weight distribution torsion forces of a larger trailer. You can brave it as others have, but you run the risk of hitch distortion and fatigue type failure over time. Along with the safety related risks of running over designed capacities.

Moving the weight to the rear is also questionable. You can do this to a degree, but part of the stability of a trailer is from having a measured portion of its mass as tongue weight. Weight behind the axle will only serve to reduce stability. If any mass is moved, best to put it over the axles.

Are you generally a weekend/short trip type camper, or are you going into this for full timing? That may steer you into the type of solution or compromise you're willing to live with.

Tongue wt is about 837 lbs. before you add a Wt Distribution hitch and personal items in your Airstream. Our 25FB exceeds over 1000 when ready for the road, plus fun stuff in our truck like a generator, Weber grill, chairs, tools blocks of wood (for blocking up in the camp ground) and then there is fuel for our truck, dog and wife. We run close to our trucks 1500 hauling capacity when hitting the road. I think you are fighting a losing battle to travel safely in your vehicle.

I recognize 837 as the Airstream specified tongue weight. It was what I use to spec my first tow vehicle. We have a FC25FB. It's tongue weight, ready to travel, is 1250 with an Andersen hitch (< 50 lbs.). I eventually traded my new F150 for a GMC 2500 because of the discrepancy.

I have observed here that the RB you interested in tends to be closer to the factory spec, but the comment about the weight of the hitch and cargo is well taken. But do not take the factory spec to the bank.

I know people who happily towed a FC25RB with an X5. They had the receiver strengthened in some way by Can Am. I would not recommend that and it would certainly be a red flag to an insurance adjustor.

No problem! A few things to consider
  • Audi specifically calls out on page 94 of the new Q7 manual to "Never mount a weight-distributing or "load balancing" trailer coupler as the vehicle was not designed for it and can cause the hitch to break off", so that's out
  • Moving weight to the back of a trailer is generally a really bad idea, it's exactly the thing that causes trailer sway
  • Audi also notes that the capacity on pg 337 only applies under 3,200 feet, they note that the actual capacity above that is 10% less
  • Unless you weighed the trailer with all of your stuff in it + water the actual tongue weight will likely be ~900lbs

It's pretty safe to say that the trailer exceeds what the Q7 is rated to tow. Look at the Expedition, Suburban/Tahoe, or Big Nissan / Infi SUV's.

20% margin or more

All this is good info to ponder. Often read that 20% safety margin (after loading everything up) would be a wise target. Already knocking on the door of full capacity or exceeding) = not safe and camping should be to relax and de-stress.

Donít think anyone would feel comfy getting in an aircraft loaded beyond rated capacity.

We will be the recipient of our own decisions.... so why not choose safe.
