It tows great, stops fine and went down a 6% grade with no issues that I could tell. Is there any advantage/necessity to getting a brake controller at this point? |

Yup, love the jetboat! Here are some pics of the cables.
Full towing review of 7000lb RV (6200 dry) I have the Curt Echo brake controller, worked great on 8 hours round trip driving. Does seem like slight delay from pressing break until RV/camper pulls, but works fine. I have a Furrion observation camera on back of RV. Would go on for a sec, off for 3, continous loop -worked perfectly with my f150. called furrion - they said german cars put out like 10 volts not the full 12. so they sent me a prototype cable (you can see in pic), fixed the problem - and also felt like brakes more responsive too towing under 50 mph was awesome, engine quite, tons of pull, great stopping power, no sway, was really nice - better than f150 v8. towing at 65MPH - wasn't a big fan. lots of sway, when car/truck flies by faster would drift a lot, definatley can't just chill while driving. using 9 chain lenghts on the weight distribution hitch. going to do closer camping trips more often - if longer ones, may rent a F250/2500 truck to pull the camper. again per my previous post, towing 4500/5000 lb boat - was awesome, better than truck. |

Thanks for the additional info! I have a few follow-on questions...
1. Regarding the sway you encountered at 65 MPH, does your WDH setup also include sway control? The WDH setup I currently use with my Ford Expedition EL has built-in sway control and I have been able to tow at 70+ MPH with no sway issues. Granted, my trailer/car setup is an open trailer so my setup would be less affected by wind resistance/cross winds from faster cars/trucks passing me on the highway. 2. I looked up that brake controller you have - pretty slick plug-n-play design and much better than the old school design I have installed in my current SUV (I currently have an older Tekonsha digital brake controller installed and it is physically installed under the dash on the driver side, close to my left leg - my SUV came pre-wired from the factory). However, is the X7 pre-wired in a similar fashion?

Found this curt echo, and glad to see is working for you. I'm going to order one and just give up on the wireless Prodigy. Our Furrion observation camera doesn't work either. Cant even get it to connect. I'm assuming either the X7 has window treatments that block the signal or the gesture control infrared is blocking the signal. Did you ever get it to work? |

Plumcrazy - your trailer appears to be nose up. Maybe this is just the way the photo was taken, but tongue should be either level or a bit nose down. I am towing 33 ft Jayco (28DSBH) with X5. I am using ProPride WDH. I have standard suspension. Absolutely pleasure to tow. It is already over 20k towing miles and always smile on my face when going to relax in the wilderness.
X7 is potentially the replacement for my X5d. I was wondering whether 40i would be up for the task with my 7,000-7,300 lbs trailer. |

Hi Bono, I think you helped me get my x5 configured for towing a few years ago. Awesome to see that you're still towing with your x5! You still getting weird looks from the truckers? Lol

Yep, looks from some truckers are priceless. Some are friendly, some are aggressive (and clueless). I got used to this.
I would really like to test X7 for towing. If there would be a diesel version in the US, I would drive it already. I am afraid that 40i would be too small and I cannot mentally spend $100k plus for a car Therefore, I am towing with $10k car! |

All that being said (and I may be preaching to the choir here), it does not mean you can't tow your rig with the X7 successfully or safely - especially when using a WDH and anti-sway equipment, which you appear to be using with your X5d setup. Car manufacturers always have engineering tolerances built into their designs and the towing capacity is no different. I don't know what the engineering tolerances are for the towing capability, but you will definitely be eating into them with your rig. Which of course means if you have an issue that could be associated with towing your "large" rig, either warranty (from BMW) or accident (from your insurance company), you may be on your own. I like your idea of doing an X7 test drive with your tow rig, I considered doing one myself. But admittedly I would be shocked if the dealer would let you do it given the size and weight of your rig. FWIW, I have a 40i and plan to tow my ~6000# rig which is a car (my current M3) on a steel, open deck trailer with built in tire rack (seen below hooked up to my now replaced Ford Expedition EL, older & lighter car, and before tire rack install). Incidentally, my old Expedition, with a 5.4L V8 has a rated towing capacity of 9000#, with a less powerful motor compared to my X7 40i. Also, while the power/torque of the N63 V8 engine in the M50i/50i may feel intoxicating and fun, if you are in it to keep your X7 for the long haul, I would recommend you stick with the 40i as the BMW 6 cyl engines have a much better longevity, maintenance and reliability history compared to the V8's over the years (and you can get a handsomely equipped 40i for around a MSRP of $85k too .

Towing capacity of E70 X5 35d worldwide was 7,700 lbs which was derated to 6,000 lbs for North America, due to the hitch. My hitch is reinforced, in particular, for use of WDH (you can google “canam rv reinforcement”). I do not want get into the discussion about litigation, insurance, etc. All valid points, but I have this researched and I am happy with the conclusions.
My trailer is 6,400 lbs dry. I am aware of BMW towing ratings (X7 is rated to 7,700 lbs for the rest of the world, by the way). It’s not about the ratings – I test drove 40i and 50i (in G05 though). I got addicted to diesel torque and I am not big fan of how 40i drives, in particular, in low revs. 50i was a monster during the test drive. Price is one issue and the range is another issue. I am wondering what range you can get when towing with 40i/50i. I am getting 14-16 mpg when towing with diesel, i.e. can easily plan driving 250-300 miles between going to the gas station. |

My comments were more for those who may be less informed or have less experience with pushing the limits of a new car, especially an expensive one like the X7. Hell, technically my rig will push the tongue weight limit of the X7, but I already know how to deal with that to ensure a pleasant and safe towing experience.... I would speculate that your towing experience with an X7 and your rig setup would be a good one (regardless of engine choice). One additional recommendation, for you if you decide to go with the X7, regardless of engine choice, is to stick with the factory hitch. The factory hitch on the X7 is so integrated with the X7 electronics and suspension, the possibility of a degraded towing experience with an aftermarket hitch seems like it would be high (although I have no personal experience with an aftermarket hitch on the X7).

Thanks! Yes, tow package is no-brainer for $550. At the same time, I understand the only difference with a tow package (apart from the hitch) are M-sport brakes in the back. Therefore, if you have M-sport brakes and add hitch, I do not expect any major issues. I expect simple coding plus OEM harness will enable all towing features.

https://www.realoem.com/bmw/enUS/sho...diagId=71_1119 For me a factory hitch was a must have option. Factory hitches are not the most common option on dealer inventory X7's, especially on an X7 with M-Sport package - but they are out there if you don't want to order a vehicle....

I’ve towed with an X5, i6 vs v8 and the 6 is good below 65mph. Once you hit 70 or steep hills, the i6 and 8 speed starts to work. But it is totally doable.
Maxed out i35...with brake controller. https://photos.app.goo.gl/NCG6famCFR3B4nXx7 https://www.towuniverse.com/tekonsha...xoCmpEQAvD_BwE If you need to tow long distances, highway speed 70+, have any hills at 55mph, get the v8 or be ok having the i6/trannywork - which I wouldn’t be afraid of. I was more comfortable with the 8 but was it worth the $$$ for the 6 times a year I used it, hard to say. What I would say, the 8 was more fun more times exponentially throughout the year, just not towing. Last edited by bjcarls; 05-10-2020 at 08:06 PM.. |

I was going to follow this basic methodology when adjusting the shank height on my WDH - but my previous Expedition did not have air suspension. And given your experience with the air suspension of the X7, and the real world load leveling capability you experienced, I was wondering if you had any additional thoughts on this adjustment process. Thanks!

X7 Towing
I will say the X7 tows well. I was coming from a Sierra 1500 with the 6.2L. Stability is much better on the X7, but the "feel" of the trailer is not as isolated from the passengers. Unlike many of you with electric brakes, this is an about 7,000 lbs saltwater boat set up with surge brakes (24' Scout). I run light on tongue weight as a product of the size of the motor hanging off the back.
Thus, you get some of "slide forward" and "slide backwards" as the surge brakes actuate. This feeling was much more pronounced on the X7. That said, the motor was very good (have the I6) and stayed low in the RPMs except at acceleration. It was a surprisingly capable tow platform. I only noted two issues: (i) get ready for serious brake dust. I have the M brake setup on advice of the dealership for heaving towing. Brakes did great but produce a veritable cloud of dust after long towing. (ii) understand how to deactivate the safety systems. First, the X7 will prevent you from backing up to a trailer hitch until you disable rear-end collision. Second, when you are backing into the water, you have to disable collision avoidance so that the X7 does not detect either the hitch (if you unplug your electrics to dunk) or the water-line at the boat ramp. Overall, I was tremendously impressed while towing a heavy rig. |

This has been a helpful discussion thread. It's given me the confidence to try towing a 23ft airstream with my new x7 40i. The trailer is 6,000 GVW and estimated 700 lbs hitch wait, but seems like with a WDH I think I should be fine. Am I crazy? I have the factory installed hitch and m brakes. The manual says 600 lbs for hitch wait. I ordered the Curt echo wireless brake controller.
I also have a 2011 x5 d, which I've only used to tow a light hobie cat, but it sounds like it's pretty capable of towing more based on this discussion thread. It doesn't have the air suspension so I imagine I need to be careful with hitch weight for it. |
