The main reason I went with the factory bar was their will be no warranty issues and the integration with the system itself. Considering how picky Tesla is about warranty claims, I'd rather not give them any other reasons to deny a claim, no matter how specious their logic might be on it. The integration with the car itself and having the MY activate the towing mode was important, more from a liability perspective. It reduces the temptation to use AP while towing. It clearly isn't designed for towing and it would be my luck, it would do something stupid while towing and create a big mess. Also who knows if down the road they might not actually do something more worthwhile with the software to actually aid when towing. From what I understand, if I don't have the factory hitch, they won't enable the tow mode.
I don't like to throw money away but saving less than about $700 (I bought it with the car) was a no brainer for me. Not to mention, if it is from the factory, my insurance covers it. If an add-on, then I have to have a separate rider to cover any accessories. Even if I had to do it over again, and my car didn't go come with a hitch, I'd still go with the factory one. When I already have 60k in the car, another grand for the peace of mind is well worth it. My wife is an attorney and they are taught all kinds of creative ways to make sure they have an edge in litigation. Having a complete factory system is once less attack vector so to speak if it ever came to it. That is another reason we bought the MY to go with the MS. Towing with the MS would have opened up even more potential issues (at least in the USA). YMMV of course. I'll pay the small Tesla tax on this one and call it a day.
Don't know, I'm not an automotive engineer. But you can do whatever you want with your car. I went with what I felt was the safest, most complete option. It's costing me $16/month.Not any more so than the drawtite version. Heres the tesla hitch, tell me whats different than the drawtite ??
My Model 3 should be delivered this week (he said hopefully). Does anyone have up-to-date info on which aftermarket hitch will fit it? Stealth?
