Then why so many folks are towing with trucks? If truck would be designed for towing, it would have low center of gravity, independent suspension, short rear overhang, etc.

I agree, if somebody is taking chain saw to campground (fortunately I did not have such neighbors so far), then pickup may be a choice. Otherwise German SUV are an alternative especially for those who appreciate good handling.

Did your BMW come standard with a 7 pin plug and a class V hitch. If not then you are forcing it. And at some point your transmission or rear-end gear box will tell on you. There have been post on here about BMW X5ís that have suffered transmission problems from towing Airstreamís. Donít get me wrong I know they will pull the weight. But the components long term are not going to hold up.

I often drink the cool-aid from the other camp. Though it's also important to take those perspectives with a grain of salt and understanding. You should ask yourself, why do so many folks tow with trucks.

It's a matter of overall design and purpose. There's competing needs and qualities.

Independent suspension is great for hugging the road. But it's also generally not as durable. For anyone that's taken a modern multi-link suspension car much over 100k, they'd know that the suspension doesn't feel as accurate as the day they bought the car. Because there are rubber bushings at each pivot point that will wear. Even without towing, with general use, these bushing deteriorate! Just consider how fast they might deteriorate if one were to use their car to tow beyond design parameters regularly. With up to 10 or more bushings at each corner, refreshing these nice German suspensions can get VERY expensive.

You need to spec the optional BMW hitch, then you get a class III receiver (typically rated to 10,000 lbs) and a 7 pin connector. Trailer Stabilty Control is standard, and was so for 5 years before Ford or Ram first offered it on their pickups. Yes, the vehicle was designed for towing.

A class 5 receiver (rated up to 17,000 lbs) seems a little overkill.

Not sure why I would need class V hitch. Yes, it came with a 7 pin connector.

The fact that somebody was having transmission problems does not prove anything. Thousands of pickup owners are having transmission problems every year, some never towing.

100% agree.

Again, 100% agree. I am willing to pay more for a better ride.

Are you referring to the receiver? Nothing wrong with using a receiver that can handle 1000 lbs of tongue weight. That doesnít determine tow capacity. Look more to axle and tire ratings.

No with transmission.
Class III Hitch is fine.

It has been very solid. ZF 8HP 75 in the latest model. That is a heavier duty version of what RAM uses (for their V8 and Ecodiesel) and is the same model used by Aston Martin for the DB11.

We have a 2017 Q7 that we tow our 2018 19FC with. I will say that when trucks pass us by on the freeway, you do feel the pull. Before buying the trailer, I contacted CanAm and they reassured me that they have had extensive experience with the new Q7's which put my mind at ease. We did hook up a Blue Ox W/D hitch which helped with the sag and gave it more stability. Through the towing process, I will note the following:

Great towing on flat ground
Ok towing up hills
Terrible on brakes

I eventually bought an F350 and we now tow it with that.

As great of a car the Q is, it really isnt meant to tow something large.

Trailer brakes should be set to slow/stop the trailer by themselves. If they were and you noticed a longer stopping distance for the rig vs solo this would be normal considering the increase in mass. I would think that a properly set up Q7 rig would stop in less distance than the F350 rig.

As a side note, it is interesting to note that if one goes with the longer (heavier) 25' AS it stop more smoothly and quickly than the smaller (lighter) 19' AS because the longer trailers have four brakes instead of just two. Another reason to go up to the tandem axle trailers.

Go big or go home. This is an example of some mistakes with the setup (German SUV having terrible brakes? First time I am hearing this) and solution - buy one ton truck to tow 19FC...

Ford recalls 350,000 trucks and large SUVs over transmission problem

The recall covers 2018 F-150 pickups and Expedition large SUVs with 10-speed automatic transmissions. Also covered are 2018 F-650 and F-750 trucks


https://www.canadianmanufacturing.co...mpaign=180406E

I guess those trucks weren't designed for towing since the transmission didn't hold up?

Camping ????

Yes, a chainsaw in a cement padded glampground would not fit the bill. West coast campgrounds though....good wind = blocked road....no rangers around to save you.

Also , physics 101, I do not care about low centre of gravity, or perforated brakes or german engineered suspension ( I drive an A4) ; if you are heading down a mountain in a rainstorm, and something happens.... which sometimes it will ie deer or moose running out in front of you, having a trailer behind you that outweighs the TV is a recipie for disaster.

Be safe out there. And if you do not carry a chain saw at least carry a good Swede saw.

I would say that it is very common that a trailer behind you outweighs the TV, even with the truck / TT combo.
