Thanks for this info, I was looking for the details on accessory hitch weight capacity a few months ago and hit a wall. Where did you read this info; was it anywhere on TMC or somewhere you could link to for me? Thanks!
I only got the accessory hitch, and am in the no more changes zone now (delivery April-Early May) so I guess it's moot for me. I probably would have gotten the tow package if I knew the weight limit was that low. I had figured it'd be a Class 1 hitch with a 200b limit... didn't even know a car maker could make a hitch that didn't even qualify for Class 1. Ah well, no cargo box for me I guess.
The information is in the Model X manual which can be found on this site. Here is the applicable information:
Supported Bicycle Carriers
To support the installation of a carrier (such as
a bicycle rack) on the rear of Model X, the
optional towing package is required. Do not
attempt to install a carrier on a Model X that is
not equipped with the towing package. Doing
so can cause damage.
Model X is designed to support a bicycle
carrier of up to 120 lbs (55 kg). When carry
bicycles on Model X, always check to ensure
that the maximum weight is not exceeded. For
example, this weight threshold is sufficient for
carrying two bicycles weighing approximately
40 lbs (18 kg) each, or four bicycles weighting
approximately 20 lbs (9 kg) each, assuming
the carrier weighs approximately 33 lbs (15
kg).
Warning: The accessory hitch is designed
to attach a 1.25“ hitch accessory only. Do
not use the accessory hitch for trailer
towing, transportation or vehicle recovery.
It is out of date as it refers to the hitch as 1.25" and we know it has been upgraded to 2".
There are cargo racks which weigh about 30lbs (this is a cheap one ) (
Amazon.com: Ironton Steel Cargo Carrier - 500-Lb. Capacity, Fits 2in. Receiver Hitches: Automotive), so you should be able to add 80lbs of cargo, unless there is something I don't understand. I can't get anyone to confirm or deny the use of a cargo carrier with the 2" accessory hitch, keeping the weight under 120lbs and the manual is specifically talking about bike carriers.
Any one have a clear answer from Tesla to this question?
