We've towed the 25' approximately 12k miles over the last 18 months, over a variety of terrain types from the Great Plains to the Rocky and Shenandoah Mountains. The X5d remains superbly comfortable and capable as a tow vehicle. With 96k miles on the odometer, the suspension is starting soften a bit, on par with my previous 2003 530i with which I did not tow.
Andy Thomson tweaked my hitch setup last week, balancing the front/rear and left/right weight distribution so the vehicle settles perfectly level onto the suspension when I connect the Airstream.
Tongue weight is running at 775 pounds, with ~175 of that transferring onto the front axle. I'm running at 35/38 psi on the X5's tires, as recommended on the door panel, staying well under maximum tire load capacities. My tires are wearing evenly, handling and braking are excellent.
Bottom Line: things are going very well. I have these occasional bouts of envy when I see all the stuff fellow Airstreamers haul in their trucks, but I get over it pretty quickly when we unhook. The X5 serves us very well.
