Here are a few things I have towed with my X5 35D. Never had a problem. I used a hitch from Europe because I did not want to cut up the bumper. That diesel just loves to tow on the highway! I don't have the third row seat option, but the car came stock with the rear air suspension.

I recently picked up this 7x12 tandem axle.

This thing hauls like a dream, only downside is 10mpg if you're anywhere near 70mph.

Whoa, with what approximate weight? Damn...

I don't think it's a stretch to say that those 10 MPGs would covert to 15 MPGs if you had the 35d, is it?

Load has little influence on MPG. I think mostly its wind resistance and engine and transmission management software. If it had a "tow" mode it might get as good as 13mpg but that's about it, I can baby it to about 11mpg if I stay around 60mph. I didn't buy the X5 as a tow vehicle, I bought it mostly to "haul" a$$. The low mpg doesn't bother me as much except that it ends up with a 210 mile range just like the M5.

That is a really nice trailer. I am looking out for a similar one, but a little bit longer, 7 X 14. It will have to be black, just like my X.
Sucks that you get 10mpg. I believe the V nose of the trailer really helps with economy, especially if it is longer, like 5 feet.

I am planning to tow a car as well with my X5, not very often, but I'll be setting it up for that.

The trailer has surge brakes, not electric. What you're looking at is the mechanical brake actuator, which is essentially a master cylinder. As you brake and the weight of the trailer pushes forward against the ball, the coupler then slides along rails and puts pressure on the brake master cylinder.

FWIW: I prefer electric brakes with a controller over surge brakes for anything over a couple thousand pounds, but that's a whole different discussion.

I found the X towed ok without a weight distribution hitch. Not ideal. I still prefer a long wheelbase truck for towing. But as a dual-duty vehicle I'm very happy with it.

Check out the prodigy wireless brake controller. I use it and it has been dependable and makes it easy to switch between tow vehicles.

I also see that you are using the hitch in the "up" extended position instead of the reduced position. Does that make sense? Anyway, words aside you are the first I have seen do this and I was considering doing this also after I just towed a heavy trailer. With the ball in the "down" side it seemed that the trailer dipped and the rear of the X5 was even lower. Did you try to use yours down also and switched it to the up position? Just wondering what others are doing.

Almost all ball mounts are designed to be mounted in either position depending if you need a drop or rise to get your trailer level. You'll see on the packaging that they're marked with both measurements. This one, for instance, is labeled "Ball Mount 3/4" Rise or 2" Drop" depending on how it's flipped.
http://www.etrailer.com/Ball-Mounts/Draw-Tite/2923.html

What you need to do is level the trailer then measure the distance between the bottom of the trailer coupler and top of the receiver. That will tell you the amount of drop/rise you need. When I do this I usually round up, or add in a little fudge factor, anticipating that the rear of the tow vehicle will sag a bit when the trailer is connected.

Here's a decent overview on how to take the measurement.
http://www.etrailer.com/faq-ballmount.aspx

It's really important to get your trailer level, especially if you're towing a dual axle trailer. When it's dropping too much in the front you put more of the load on the front wheels while the rear wheels are lifting a bit. It also shifts more weight onto the ball, which will be exaggerated when you go over bumps.

Has anyone noticed that when the trailer is connected their side mirrors don't auto dim? I was towing home from the track in the dark tonight and my mirrors weren't dimming. After I dropped off the trailer they were dimming gain. Fluke or by design?

if it is true that would be great as this would mean the auto dimming could actually be controlled manually in one way or another... sometime I really like to remove the auto dimming to get more clarity.

I noticed this as well. I thought it was because the trailer blocked the interior rear view(sensor) mirror.

Good thinking. I bet you're right.

I get 11-13 towing @70-75. The main factor is wind velocity and direction.My trailer is an 18' V-nose, and the total deadweight including race car is 4500 or so. This is 1-2 less than I got with my Tuareg diesel, which should be pretty close to the 35d. My X5 35i tows better than the VW did overall, though, mainly due to WB/ suspension differences. I like diesels, but the 35i is fine for towing and I feel no need for a diesel.

I have towed various sizes of U-Haul trailers in the past with my 2010 X5 3.0, mostly when friends are moving and need help but don't have a truck with a hitch. No complaints since 2010..

My X5M tows like a dream; can't even tell I have ~6k pounds behind me while towing my race car. I'd like to add electric brakes, as the trailer is already equipped with it. Big dollar install of the hitch (and computer reset) from the dealer, but thankfully I was able to negotiate it in with the original purchase for cost. ~11mpg in efficiency mode while towing, and just under 10mpg in M mode while towing.

While we are at it, what are 0-60 numbers with loaded trailer?

Due to AWD and rear wheel bias, the point of tear will be somewhere between rear wheels and the trailer.
