Glamping, a word that combines the terms, glamour and camping, refers to going to campgrounds but having the amenities normally present in a hotel.
Tesla has an interesting Cybertruck trailer concept. It's a large trailer about the size of a tiny house. It’s a nice looking trailer and it reflects the angularity and aerodynamic shape of the Cybertruck. In Cybertruck patents, Tesla shows the Cybertruck pulling a weight of 20,000 pounds, however the official Cybertruck specs say it can tow more than 14,000 pounds. I interpret that as a max weight of between 14,000 pounds and 15,000 pounds.
Now, remembering what we learned in high school physics, you’ll recall that how much weight a truck can tow has three components. The truck has to overcome rolling resistance, air resistance, and gravity. Now rolling resistance increases gradually depending on both the weight of the trailer and the speed you’re trying to tow it. It’s a linear increase. While there’s more rolling resistance at highway speeds than there is at parking lot speeds, it’s not all that much more.
Then there’s air resistance. That’s not related to the weight of the trailer at all. Air resistance is related only to the cross sectional area of the trailer, the aerodynamic shape of the trailer, and the speed of the tow. Air resistance increases as the square of the speed, so that’s a much more significant factor at highway speeds than at low speeds, but it has absolutely nothing to do with the weight of the trailer.
A few months ago, Ford came out with a publicity stunt involving a prototype electric Ford F-150 Lightning towing a million pounds of railroad cars when they were empty. Then they loaded one and a quarter million pounds of pickup trucks into the railroad cars, and the electric Ford towed all that, too (you can watch the full video below).
It was supposed to demonstrate something. All it demonstrated is that Ford likes to lie to people who don’t remember the physics they learned in high school.
The tow was done at slow speeds on steel rails with steel-wheeled railroad cars. Of all the land vehicles currently in use in the US, trains have the least rolling resistance. Maglev trains have less rolling resistance, but they’re not in use in the US. And anyway, maglev trains don’t roll. They float on a magnetic field. So all the electric Ford had to do was overcome a certain small rolling resistance. Admittedly, you or I would have been unable to start those train cars rolling by pulling or pushing by hand, but probably any pickup truck could have done it. It didn’t have to be a Ford.
The reason there’s a weight limitation for towing a trailer is that roads aren’t level. On hills, there are two considerations. The truck needs to be able to tow the trailer up any hill it might come across, and it has to be able to control the trailer when going down any hill it might come across. So if Tesla says the Cybertruck is rated for 14,000 pounds, then it really shouldn’t try towing 20,000 pounds even if that seems possible on level ground or mild hills. But there is a way around this limitation in the era of electric vehicles.
What I’m going to tell you does not come from Tesla, or any knowledgeable source. It comes strictly from my imagination so take it with a grain of salt.
The way the Cybertruck can safely tow a load that’s higher than its rated maximum towing weight is if the trailer has its own batteries and its own electric motor(s). There would, of course, have to be coordination. The trailer would have to respond to the truck driver’s control input, but that’s not difficult to arrange. If the trailer had batteries and motor(s), the range between recharges would not be degraded by towing. If the trailer could be recharged separately from the Cybertruck by a second Supercharger stall, then the length of time to recharge wouldn’t be prolonged.
Now let’s talk about what the trailer could include. I looked up the weight of a standard 30-foot travel trailer. The weight averages around 5,800 pounds. So that leaves plenty of room for amenities. The trailer could expand, for example. It could expand upward when parked, or sideways. Lots of travel trailers do that. So instead of being 30 feet by 8 feet, it could be twice that. Perhaps it could expand sideways on both sides, That would make it 30 feet by 24 feet.
Add to that interior room, an extra roof to cover an outdoor patio, another 8 feet by 30 feet. Cover all that roof with solar panels, and you’d have lots of electricity while you were at the campground. Excess solar electricity created in the daytime would be stored in the trailer’s batteries at night.
Then there are other amenities. In addition to the normal water tanks for drinking, bathing, and other cleansing purposes, there could be a hot tub for two. That would hold 150 gallons of water, 600 pounds. Tesla is good at making heat pumps. Heat pumps can be used to heat or cool the trailer depending on the outside air temperature. If the trailer is parked near a stream or a lake, the heat pump might be able to exchange heat or cooling with the body of water if that would be more energy-efficient than exchanging heat or cooling with the outside air.
While traveling, there should be enough outside video cameras so that the driver would not have blind spots next to or behind the trailer. These should sync with the Cybertruck’s display screen.
The Ford F-150 Lightning has a helpful feature for hooking up the truck to a trailer. The driver first cranks up the trailer’s hitch to the proper height. Then he drives the truck to the front of the trailer so he can see the trailer hitch in the rear camera display. At that point, the truck itself backs up until the truck’s trailer hitch is properly aligned with the trailer’s hitch receptacle. Tesla should do that for the Cybertruck in a software update.
Finally, there should be Internet access via Starlink.

With most vehicles moving on to Tesla’s 2025.14 Spring Update, we’re now taking a look at all the undocumented features that were discovered during Tesla’s 2025.8 update.
While these features tend to be smaller in nature, some of them are just as valuable as the features outlined in Tesla’s release notes in the vehicle.
This update includes changes such as improvements to maps, trip meters, and Rainbow Road. Let’s take a look at all the undocumented features in Tesla’s 2025.8 software update.
New Map Icons
Not a Tesla App
Icons on the map are being redesigned to be rounder and easier to see. They now feature a white border to make them pop out against a colorful background, which is especially better when using satellite views.
This feature started rolling out slowly but should now be available to everyone.
Trips & Odometer
Not a Tesla App
The Trips display has been improved to show more precise information, and a new metric has been added.
More Precision: The trip meters will now show values with a tenths place when they’re under a certain value. That means that the Current Drive and Since Last Charge trip meters will now show a fractional kWh and a mile. This is especially useful for Current Drive.
The Current Drive meter is automatically reset when your vehicle comes out of park so that it can track your current drive, while the Since Last Charge meter automatically resets after a charging session completes.
More Data: In addition to added precision, the Current Drive now features a new data point. kWh is now shown for the current drive, just like the other trip meters. Previously, the Current Drive showed minutes instead of kWh -- it now features both.
These changes affect the Trips widget in the Model 3, Model Y and Cybertruck. While the added precision is also added to all vehicles under Controls > Trips, the new kWh metric for the Current Drive is only displayed in the small widget.
Additional Tool Tips
Not a Tesla App
Tesla has added some additional tips to the screen that show up in certain cases. For example, if you’re playing audio over Bluetooth, Tesla will suggest that you use their built-in music apps instead of streaming through your phone.
Destination Charging
Not a Tesla App
Destination charging icons are now visible on the map when you have Points of Interest enabled. You can enable Points of Interest by tapping on the map and choosing the Points of Interest icon on the right side near the satellite imagery icon.
Some destination chargers may charge a fee, while others may be open to the public or exclusive to paying customers.
Navigation Improvements
Not a Tesla App
If you're using Tesla's navigation system with voice guidance enabled, the spoken directions will now stop immediately when you end the trip. Previously, the spoken directions would continue being played until the phrase was completed.
Improved Rainbow Road
Not a Tesla App
The rainbow road feature has been greatly improved in this update with FSD. Rainbow road, which can be enabled in the Toybox app, now changes the vehicle's path when on Autopilot from a blue path to a rainbow one.
Previously, Tesla had to overlay the blue path on top of the rainbow colors because rainbow road didn’t support all the features of the path, such as showing chevrons when slowing down rapidly.
With this update, the rainbow path now incorporates all the same features as the blue path when FSD is active.
In addition, if you start Rainbow Road by tapping the right stalk four times, audio will play. Unfortunately, the sound couldn’t be stopped until it was completed before, but with this update, you can now stop the audio by reducing the volume with the left scroll wheel.
Additional Transparency Effects
Not a Tesla App
On Intel vehicles, several modules didn't include a transparency effect. This was primarily due to Intel cars not using the blur effect since it could slow down the infotainment unit.
With this update, Tesla has enabled the transparency effect across a set of modules. Notably, this fixes the issue when using full-screen visualizations where the music player had transparency, but the navigation module on the right did not.
Transparency has also been added to other modules that are displayed over the map, such as the list of Superchargers, destinations, search results, and the ETA / End Trip module displayed at the bottom.
Note: Due to the lack of the blur effect on Intel due to performance reasons, these changes could make some text more difficult to read.
No Phone Key Graphic
Not a Tesla App
The graphic that's displayed in the vehicle when it doesn't detect a phone key has been updated. Tapping on the blue text at the bottom displays the old animation showing you where to tap a key card.
Bluetooth Player
Not a Tesla App
The Bluetooth app typically only displays the connected devices and a button to connect a new device. There was a lot of white space, since there wasn’t much other information to display.
With this update, Tesla is making it easier to jump to another source by displaying available music streaming services underneath the connected Bluetooth device.
Tapping a music service will jump to the selected service.

Next Update
Tesla’s next update is the 2025.14 Spring Update, which has now rolled out to more than half of the Tesla fleet. If you’re still waiting for it, rest assured that you should be updated soon. If you’ve already updated, be sure to check out the undocumented features already found in the 2025.14 update.
Tesla has issued a strong denial in response to a Wall Street Journal report (Paywall) which claimed that Tesla’s Board of Directors had initiated a search for a new CEO.
In a statement posted directly on Tesla’s X account, Board Chair Robyn Denholm denied the report unequivocally. As per the statement, Tesla’s board did not reach out to recruiting firms in search of a new CEO.
Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company.
This is absolutely false (and this was communicated to the media before the report was published).
The statement reaffirmed the board’s position on Tesla’s current leadership and that the board is highly confident in Elon’s ability to continue executing Tesla’s plans and future growth.
This confidence behind Elon follows his recent statements made during the Q1 2025 Earnings Call that he would be stepping back from the Department of Government Efficiency (DOGE) in the coming days and significantly reducing time spent there. Instead, he would be returning to focus on Tesla’s operations and the upcoming deployment of Robotaxi.
Shortly after the denial was posted, Elon Musk also commented on the report, specifically tagging the Wall Street Journal and criticizing their handling of the report.
It is an EXTREMELY BAD BREACH OF ETHICS that the @WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors! https://t.co/9xdypLGg3c
We’re glad to see Tesla and Elon set the matter straight, but there could have been a better way to spread this message and maybe even prevent the report from WSJ from going out.
We recently published an opinion piece on why Tesla needs its PR team back, and this specific incident is a good example. Relying solely on platforms like X for critical corporate communications - and in this case, late at night (1 AM EST), with limited reach outside the existing follower base seems like an ineffective way of communicating important company information.
We’d love to see Tesla really put some thought into managing its image, as it seems that several recent reports from major financial news organizations have apparently been wrong.
Either way, the board’s stance is clear - there is no active search underway, and Elon has the full backing and support of the board to lead Tesla toward the future.
