Bullied,
This is our set-up... 2016 T6 & 1972 29ft Airstream.

I installed a draw-tite receiver (from etrailer) with the Volvo towing module and harness. I also had it reinforced (at CAN-AM RV) with a bar running under the muffler back to the frame in order to use a weight-distribution hitch. The hitch itself is rated for 6000lbs (non weight-distribution) and 900lbs tongue weight. I'm not sure of the weight of the trailer, the dry weight in manual states 4900lbs so with our gear and some water etc in the tanks I put it around 5500lbs but I never got the chance to weigh it this summer.
As you may know the XC90 tow rating in Europe is rated at 6000lbs but only 5000lbs in North America so I'm certain that some may blast me here for my set-up and frankly I was a little concerned myself.... but now after pulling the trailer for about 5000kms this summer on its maiden voyage it was nothing but a dream. We traveled all types of roads and weather including twice through the White Mountains without a single problem, in fact there wasn't one time that I felt things got sketchy. I traveled pretty well at 100km/hr and a little slower up the hills, but not because the vehicle couldn't manage but just to save on fuel. The fuel economy decreased from about 10.5l/100km to around 18l/100km, which frankly was still decent in my books considering this is what my X5 V8 used to suck back driving around the city. Overall it was so nice to have the space for my 3 kids (3rd row!!!) and a great vehicle to travel around in once we dropped the trailer.
Some thoughts so far...
- I would like to add an transmission oil cooler but from what I can tell the typical aftermarket set-up won't work as it seems that the coolant travels back to the transmission vice the oil moving forward and passing through the radiator. Perhaps I'll speak with the dealer next time I'm in if they have any ideas on this. Even a temp gauge would be helpful for peace of mind. I did play around with different drive settings and mostly settled on dynamic mode and shifting into manual on hills to keep the revs around 3000.
- I ran the vehicles tires at 47psi for the increase in load, they didn't seem to mind and heat was not abnormal. Trailer tires were at 50psi.
- I'm using a wireless proportional brake controller (Prodigy RF) that worked great and means that you don't need to hardwire anything into the vehicle. The controller just plugs into the 12V outlet, all the brains are attached the trailer.
- I think the trailer (being an Airstream) helps due to the aerodynamic shape for both the head and cross winds. I have 2 sway bars and the Volvo towing software apparently auto-corrects if trailer sway is detected. I have no idea if this feature was activated while we were driving but the set-up felt solid.
- I'd be interested in thoughts about the Polestar software upgrade if this would provide for improved automatic shifting points.
Well I hope you find this inspiring... We bought this trailer just 3 weeks after buying the XC90 and in the dead of winter. When spring finally came around I completed about 400 hours of work restoring the underside, interior, windows and electrical/utilities. It was a big job but the results are great and definitely going to be the base for a lot of family memories.
