I ended up going with a Curt Echo. Mine came with a rubber strap (was stuffed inside the female end). I borrowed a friend’s car hauler trailer to test it before I pick up the camper next week. It seemed to work well. However, I did order the override button. I’m not going to have the app open on my phone for 2 hours driving just in case I need to hit the brakes on the camper only. The other thing I realized is that the mirrors on the X7 are WAAAY smaller than on my Sequoia. I backed up to my buddy’s big camper and couldn’t see shit around the sides. So I think I’m going to get some aftermarket extensions. Does anybody have recommendations? |

After a year of unsuccessfully waiting for Furion to make the adaptor available to the general public, I am looking for an alternative. Does anyone on here use the Haloview camera set-up? If so, any issues with the BMW or adaptors required?

Curious with folks who have WDH setup on vehicle with Air Suspension, did you install the hitch and did the height measurements initially with air suspension at lowest level? I'm having some issues with weight distribution and I thought it maybe related to air suspension taking on almost all of the tongue weight instead of being distracted via WDH. Mine was setup at mid level on a X7. Thanks.

With the air suspension re-enabled, it leveled out my X7 even more (it was already very close to level), contributing to an even smoother ride while towing. Sounds like your issue could be you just have too much weight too far forward on your trailer. Or you are carrying too much weight in the back of the X7 while towing (or both). Those two variables contribute to tongue weight as well - and the air suspension may not be able to compensate.

I heard some horror story where someone's air suspension system got ruined due to self leveling feature constantly adjusting/compensating the weight exerted by WDH. Has anyone experienced or heard this? Is there a way to turn off self leveling feature while leaving air suspension for ride comfort?

A WDH system is a "set it and forget it" system. When setup properly, along with proper trailer height and trailer weight distribution, it allows the additional rear weight of the trailer to be better and evenly distributed across the front and rear axles of the towing vehicle. This in turn allows the tow vehicle to ride level, which leads to a smooth and safe towing experience. The air suspension further assists by making adjustments to the suspension to keep the towing vehicle level. So in theory, if your WDH system is setup "perfectly", the air suspension should not have to do anything (but nothing is perfect of course). Furthermore, the X7 air suspension is designed to work with towing, as it has a towing option (not all air suspension systems on all vehicles are designed to work with towing). I highly doubt towing would be the cause for any type of air suspension failure, especially if your tow rig is setup properly (proper tongue weight, proper WDH setup if you have it, etc). As far as turning off the load leveling aspect, I will say it can't be done. Or at least I have not seen a specific option to do so (I haven't looked either). You could disable the air suspension altogether while towing. But I would not advise that as the X7 with air suspension from the factory (you can actually get X7's w/o air suspension in other markets) is designed to be on when driving. So bottom line, I think you are over thinking this. It is not that difficult to setup your tow rig properly for safe towing with the X7. Also, a WDH system is not required to tow, but in general it is advised to have one if you are towing heavier loads like large campers, larger boats, or cars to name a few examples. But if you don't feel comfortable doing it yourself, then just take it to a professional for help with your setup.

On a related question, I realized that X7 has a very low front axle weight rating, on my particular vehicle, it says GAWR front is 3020 lbs. Last time I drove through a CAT Scale, it told me my front axle weight was 2720 lbs (this was without any trailer attached, so just the car and myself sitting in the car). Once I have wife and kids added to the car, this number will get even closer to that 3020 limit. My question here is whether this car is really designed to use with WDH which can easily added 200+ lbs of weight to the front axle and blow up the limit. Anyone have thought about or experienced this? |

When you hitch up the trailer, load on the front axle decreases. As an example it can drop from. 2700 lbs to 2500 lbs. With WDH you can transfer 20-30% of tongue weight. You should have enough margin on the front axle.

I’m looking into towing about 6000# of trailer and car with my X7 M50i. The brake controllers (like Curt Echo) are mentioned here. My question: will the X7 control the trailer’s electric brakes through the hitch’s pin connection? And if so, are you adding the brake controller for additional control of the trailer’s brakes?

This only works for trailers with electric brakes, which is the case for most trailers that are not boat trailers (which use hydraulic brakes). Of note, all Uhaul trailers use hydraulic brakes in case that is the trailer you plan to use to tow your car (so the Curt Echo unit would not be needed).

As I said before, I ended up going with the Curt Echo brake controller. I also bought the override button….just because. All of it worked great and is super clean. I set up the app, started pulling the camper and made a few adjustments, then I was on my way. The override button worked well too. I stuck it next to the gear shifter. When I was finished with the trip, I removed the button, put the sticky cover back on, and put it all away. It’s a bit pricey for towing occasionally, but not having to drill holes, or rewire anything made it well worth it. For a reference, this camper that I rented is 5,500 lbs empty. My guess is that I was at about 6,000-6,500 lbs.
