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.

In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
