Very nice. I tow my track car, and try to avoid driving offroad as best I can.

My '04 4.4 tows extremely well. When I was pulling my 911 on my open aluminum trailer it was no big deal to set the cruise at 75 and go for hours at a time comfortably.

Unfortunately my new enclosed trailer has max'd out the tow rating of the X5. By the time I load the car (2450 lbs) into the trailer (2900) and throw in 8 spare wheels and tires (350), tool chest (250) and spare parts (250), I'm at the tow rating. Sure, the engine has the power, but I can't come close to being able to see around the trailer. I've tried the aftermarket mirror extensions but at highway speeds they vibrate so much that anything along side is just a blurr. Too bad because the 4.4 pulls so well, and being able to leave the Steptronic trans in 5th at highway speeds is the perfect powertrain setup. I can pull at 70 pretty easily, just can't see. So sadly I'm now looking at changing vehicles- Yukon Denali or Infiniti QX56. Might just sell my 528 and keep the X5 as my daily driver though.
