I am looking at the MB ML350 or GL350 to tow the '07 Intl 25FB that I just purchased. Did you do any mods to your GL? How long have you been towing with it? Any years I should avoid if I buy used? I am worried that there is little wiggle room with regard to weight limits with the MB's but can't see myself in Yukon or similar other truck based large SUV. I appreciate any insight you can offer based on your real world experience with the MB.

Thanks!
Kelly

Our 2009 X5 diesel has been a great overall car, and an impressive tow vehicle. We wanted a medium-sized do-it-all SUV, and this is as close as we found to such a thing.

Only scheduled maintenance in 4.5 years, except for one diesel system issue, which was engine control software rather than hardware, and was repaired under warranty. I kept the 255/55-18 factory run-flat tires, and they behave well under towing loads.

I deliberately purchased the X5 with only the basic premium package, and did not choose electronics-heavy options, or air suspension, for the same simplicity and self upgrade paths mentioned in this thread. The dealer installed factory hitch and brake controller have had no issues. As others have noted, the problem areas for BMWs tend to have been in upgraded electronic systems.

We have been towing with it for a year and a half, in all conditions except extremely mountainous terrain. Towing mileage is 15-18 MPG (15.6-13.0 litres/100km), and plenty of satisfaction from 425 lb-ft of torque. The current cost of diesel fuel doesn't make it as a great cost-per mile value as when we bought it, but the non-towing mileage of 24/29 city/highway still beats our old gas V8 SUV by a healthy margin.

I can certainly recommend this choice of tow vehicle.

Question on X5

Confused about using a BMW X5 as a tow vehicle for a 7400# (GW) 25' Airstream? Towing capacity for an X5 is 6000#. I presently have a 2011 Sequoia, looking at Diesel Cayenne, MB diesel GLASS 350 and Infinity QX 80. Is a BMW X5 Diesel or V8, actually an option to pull (up to) 7400#?

It's worked for me since June of 2001 (ASCL 31' with GVWR of 8,300#). See my avatar and do a search on "withidl".

I consider it a reasonable option, with some qualifiers.

1) Consider the strength of the receiver. On the E53 built up to 2006 (withidl has one, I had one) it was very solid. On the E70 (up to 2013) or F15 platform (debuted in 2014) I would look into the receiver attachment and decide if any hitch reinforcement was required.

2) Consider total actual payload as compared to vehicle GVW and curb weight. Pay attention to axle loads and tire load limits.

3) Recall that the X5 has a 7700 lb tow rating in other markets, where the receiver may be different (although it has the same attachment point).

Of course you can always check out Andy Thomson's posts on here or of course his dealership (Can Am Airstream) website, for info about towing with "alternative" vehicles. Something that he is somewhat of a "master" at setting up those combos. He also regularly writes in "Airstream Life" mag.

2014 BMW X5 Towing Hitch

Hi all - I am taking delivery of a new X5 and would love some help on the hitch install.

If you did proceed with the 2014 X5, what did you go with for a hitch setup? Looks like the BMW OEM Class III hitch has an integrated ball and not a 2" receiver for a shank and sway control set up.

For many reasons, I'd prefer my current sway control I have now.

Thanks for the insight.

Urban71-We are going to Ontario, Canada to get Can-Am RV (Andy Thompson) to install a hitch receiver from scratch. It will be much stronger than the BMW hitch. I would recommend you check into this option.

BMW X5 Tow Vehicle

Best of luck with the install. We'll be sure to research that.

Urban71- there is more to it with the BMW than just installing the hitch- the X5 needs to be reprogrammed to know the hitch has been installed - so when the TV is hooked up to the TT- the X5 with change the shifting patterns, engine cooling, Xdrive dynamics, etc....

To txdxrider's point, I know on my 2011 X5 35d there is an auxiliary transmission cooler built in by BMW at the factory that can only be activated if the car has been reprogrammed. I went with the factory receiver install and wiring harness for the 7-way connector so I can take advantage of it.

BMW doesn't recommend using sway controls...it's an open debate as to why on various towing forums. I tow with my Reese Dual Cams and haven't experienced any issues.

Great input. I'll get with the parts and service guys to make sure we are utilizing all that the x5 has. It's interesting how little they put out there about towing options. Like spelunking for info!

RacerX, do you have any documentation on that cooler? That is different than my earlier model X5, and I haven't seen that before. The reprogramming on earlier models did not add any code, but simply allowed the vehicle to recognize the existence of the trailer wiring module, which then allowed access to the trailer stability control mode of DSC, turned off the rear PDC, and on some models, changed the rear camera mode. All models of X5 have and use the transmission cooler with or without a trailer AFAIK.
