Audi RS Q8

Hello! Very excited to be posting here as new owners of a 27' Globetrotter. We also have a beloved, new Audi RS Q8. We're thrilled to participate in Air Forums, finally!

Let's talk towing. The Audi is a V8 AWD variant of the Q8 with 591HP/590FP torque and a factory installed tow package rated to 7,700 lbs. Also worth noting that this car has air suspension with about 12 CMs of adjustment, and a "trailer mode" in the air suspension. Audi even did track testing with a trailer on this car apparently.

The Audi is an everything car for us: fast, functional and luxurious. We want to be able to go skiing, tow the Airstream, hit the track, and go offroad to reach distant hikes-- all with the single vehicle. We believe the RS Q8 is exactly that, with one issue. We're about 100lbs over on tongue weight.

Audi RS Q8 with factory hitch receiver:
GVWR: 7,700 lbs
Tongue weight: 770 lbs

Our 27' Globetrotter:
GVWR: 7,600 lbs
UBW: 6,258 lbs
Tongue Weight (with LP & Batteries): 871 lbs

So we're obviously 100 lbs over on tongue weight. The dealer tried a weight-distributing hitch (Blue Ox) and none of us liked how either vehicle was holding the weight. So we tried a standard drop hitch with 4 height options. They fitted it, liked what they were seeing and let us drive off the lot, to their credit noting the risk of the tongue weight overage.

We've tested hitching with the air suspension's tow mode on and off, and it definitely seems much better with the air suspension in tow mode, with the suspension seeming to keep the car and weight more stable.

This combo (seemingly) handled very well in our only trip so far. We felt the wind from passing 18-wheel trucks on two lane highways, but didn't feel any sway or loss of control. The vehicle never felt low on power and temperatures were green while towing over a mountain pass during moderate outdoor temps. We didn't hear any groans or creaks, thankfully.

We've talked to the fine folks at Can Am; they say reinforcing can affordably be done, and allow us to tow a 27' without concern. Too bad we're in the United States and the the border likely won't be open until 2022. We'd love to be able to tow with this vehicle until then.

We're thrifty and typically bring less when we RV. Does that mean our trailer's actual loaded weight and therefore tongue weight could be potentially lower than 770 lbs? Perhaps if we only towed with the black and grey tanks empty, that could conceivable push the tongue weight below 770 lbs? Can tongue weight of a specific vehicle/loaded trailer be measured?

So... I ask you, wonderful people of Air Forums: are we crazy to tow with this car or have we found our true love in pairing these two vehicles? Please help us in realizing our dream! Thanks in advance.

(And in case you wondered: we do plan to swap out those 23" wheels and tires for something smaller and a little more practical.)
