I'm sure you've found it but there is a pretty extensive L2 charger network in Canada called the Sun Country Highway...

Yeah, thanks for the tip! Looks like these are all on plugshare.com. Can't wait to start using them! Hopefully my Model X will be delivered without the delays many others seem to be experiencing.

Also to get full use of amperage on the Sun country 80A chargers you need to press the start button. Your car will automatically charge but at a lower rate if you don't press the button.Yeah, thanks for the tip! Looks like these are all on plugshare.com. Can't wait to start using them!

You can keep an internal combustion engine in there for a week?
We're in Bozeman and are planning a trip to Santa Fe in August. Picking up our X next month. Let me know when you plan to hit Bozeman and we could swap tales.

Excellent, will do! We currently expect to be in town on the 21st of August. I'll message you when we're closer!

Nice! I was trying to decide between a Yeti and something that could plug in to the 12V outlet. Anyone have any idea how much of a hit on range you get from running a cooler in the back?

As I'm planning my first big road trip, I'm curious how busy ARE the Superchargers? Is this an issue yet, or one that we're just anticipating as the Model 3's start pouring on to the roads in a couple years? How often have you pulled in to a Supercharger to find every stall in use?
Just see how much energy the cooler uses and divide that by your Avg Wh/Mile
There are a lot of threads on this (focus on the Model S ones, the Model 3 jumbo-thread is mostly guessing what the future might look like).
General summary - in most of the country, they're almost always readily available. On the West Coast, especially in California, there can be congestion during peak times, which include holidays and weekends. This is especially true on Sunday afternoon/evenings, it seems.
I've waited a few times, never longer than 20 minutes. But I've used them extensively up and down the West Coast, so the times I've had to wait rank in the less than 1% range.
I have not had much success with the 12v portable coolers. They don't use that much energy and they don't cool down very well. A great one would have to use some serious energy like cold plates installed in a boat. A great insulated cooler is a simple fix.Nice!

Maybe some back-of-the-envelope math is in order.
Doesn't make sense considering it's adding to energy overhead and is unrelated to distance traveled. It's more like wh/hour.
For that back-of-the-envelope math: Since you're limited to 12v with those power sockets, and up to 11 amps for continuous power, I would expect most 12v coolers would use at most 10 amps x 12v or about 120w of continuous power. However some quick research on Amazon has shown that most actually only use about 40 watts, and are not great at cooling things down but rather keeping cool things cool.
Assuming continuous cooling, you're looking at 40wh/hour of power. That means you will use 1kwh of power after about 25 hours of continuous use. So if you're looking at a 3 hour drive at about 60 miles/hour, you will travel 180 miles (reasonable distance between supercharges), you're looking at using an additional 120wh of power over that time...
Even adding 20% for potential energy losses and an extra hour for time before leaving and after arriving, you're looking at most at 192wh of additional energy consumed, or a loss of about 0.56 miles of rated range on a Model X, or ~0.3% of the distance traveled or ~0.2% of the total rated range of a 90kwh Model X.
So it's not a noticeable hit to range, unless you run out of juice a half mile from the supercharger

Awesome, thanks for helping with the math. I'm still trying to wrap my head around all the definitions and relationships of Watts, Amps, wh/hour, wh/mile, etc.

Good to know, and about what I expected. Hopefully Tesla has a long term plan on supporting all those new vehicles, and our government will get on board with more support for EV's. Elon Musk for President!
I did a 1200mi trip which would usually be 9hrs but took 14hrs. With P90d 250mi range was more like 180-200. It was cold and I have 22" wheels plus some hills. Since chargers where so far apart I had to do a full charge which took over an hour each time. Another problem was I had to drop my speed to keep from running out of charge before next SC. So if you take your miles and divide by 45mph you come to the average I had. I was not prepared for this. Unfortunately for me, I was in the danger zone of range between each SC. Things are already better since last trip with a new SC opening on my route. Driving My X, I would not want to travel over 150mi between Chargers. Anything more would make be worry about all the above issues.
