I havent officially weighed it, but I calculate my boat/trailer combo with 50 gallons gas, cooler and some misc at about 5200lbs.

Previously towed with a 1/2 Chev pickup. The pickup struggled. My X5 actually has a higher tow rating by 300lbs.

The air suspension is wonderful! Levels the load instantly when hitching up and keeps the vehicle level. I can accelerate as fast towing as any average vehicle without a trailer. No sway or feeling of trailer overpowering the X5 at all.

I shift it in manual mode however, as the transmission automatically compensates for the load, but I dont like how long it holds the shift points. I shift at 3k RPM and get 12-14 MPG.

Simply put, its a FANTASTIC tow vehicle. Not many vehicles out there with the pedigree of the 4.8is coupled with the towing capability.
