Preparing to Tow With A Tesla Model X

One of the reasons that we bought a Model X rather than a Model S was so that we could tow our camper. Spring is coming and we'll be getting the camper out soon to prep it for our summer fun.


In addition to pulling the camper, the tow package has other advantages too. We can mount the bike rack there and we can rent a trailer if we need to move large items or hardscape. I had been driving a Honda Passport to pull the camper. I traded it in for the Model X. There were a few things I had to learn when we switched to towing with the Model X.

The optional tow package comes with a proprietary hitch receiver. I suggest installing the receiver and hitch before you need it so you can take your time and learn how to do it. The unit has a twist lock system that installs vertically, this is different than any that I've used previously. Here's a video that explains the twist lock system. Once you figure out how it works, it's nice, but here is a small learning curve.

At the rear of the car, there's a cover underneath that removes to expose the dock for the hitch receiver. This dock is attached to the frame. This is where you insert the hitch receiver. Once it is installed, you have to lock it into the dock.

There are three main parts to this process:
  1. Hitch Receiver - This is the part that Tesla supplies when you buy the tow package. It comes in a zip case; sometimes referred to as a hitch box
  2. Ball Mount - This is the bar that goes into the Hitch Receiver; sometimes called ball mount shank or hitch bar. Sold separately.  
  3. Hitch ball - This is what the trailer attaches to. Sold separately

In the US, there are three common sizes of trailer hitch balls, 1 7/8", 2", and 2 5/16". The 2" ball is the most common for light trailers and the size we used with our Model X. In addition to the ball, you will need a mount which fits in the 2" receiver which holds the ball at the correct height for the trailer to be level, and pins to secure the mount. You can buy the ball mount and ball separately and assemble them, or you can buy a kit like this one that comes preassembled with both of them plus the pull pin and cotter pin. I recommend a kit.

Unfortunately, it is not as simple as just installing the ball mount. The bumper of the Model X is lower than it is on most trucks, so to put the ball at the right height, you have to flip the ball mount over and remount the ball such that it is raised, rather than dropped.

To get the ball loose from the receiver and to remount it, you are going to need a really big wrench.

After you have the ball mounted in the raised position, I suggest that you lock the threads with Loctite Red or a similar product. This will be rattling around for miles and miles, a little loctite is a good idea.

Now that you have the receiver installed and the ball at the right height. It's time to look at the electrical connection. The Model X only has one type of trailer electrical hookup, the 7-way round electrical connection. If your camper or trailer uses the same type, you're ready to go. If, however, your trailer uses a 4-pin electrical connector, then you'll need an adapter like this one.

Next on the list are the safety chains. One thing that I didn't like about the Model X tow setup, was the location of the safety chain connectors. They are very hard to reach. This made hooking and unhooking the camper a difficult job. You can see where they are located in this photo:

To avoid sliding under the car every time I wanted to connect or disconnect the safety chains, I installed a pair of safety chain extensions. These are rated for 8000 lbs, while the X is only rated for 5000 lbs, so I feel safe using them and it makes the connect/disconnect process much easier.

That's it for the basics. You are ready to hook up and roll.

For the pro-towers, here's one bonus tip. If you expect to tow for more than 1000 miles each year, I'd consider adding a Hitch Tightener like this one. It will stabilize the ball mount and stop it from wobbling in the receiver. This will make it smoother, quieter, and reduce wear. Live the adventure!
