Thanks for sharing the picture. I see you are using a weight distribution hitch. What type is it and how do you like it? There isn't much information out there about BMWs and WDH but it appears that the WDH is not recommended on the X5. I plan on towing a 23 ft Jayco that weights 4200 lbs with my 35d and I'm not comfortable towing it without a WDH. Any input would be appreciated.
