Glamping with Tesla's Cybertruck and trailer concept

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.

Tesla Cybertruck November Update: No More Wraps, New Crossbars Accessory, Available in Inventory, and Faster Charging

Not a Tesla App

There’s been a spade of Cybertruck announcements that just came up all at once, so let’s see what the polygonal truck is up to in the month of November. We’ve got a variety of topics to cover, starting with some disappointing news about Tesla’s in-house wrapping services, which are being discontinued for the Cybertruck. But don’t worry — there’s plenty of good news to follow.

No More Tesla Wraps

Tesla no longer offers wraps for the Cybertruck as an option for US customers. Tesla began wrapping vehicles earlier this year but stopped offering wraps for the Cybertruck as of November 13th.

This comes after Tesla previously reduced the color options for Cybertruck wraps from seven to five. However, this isn’t too big of an issue—there are plenty of companies that specialize in vehicle wraps.

The reason Tesla stopped offering wrap services for the Cybertruck isn’t clear. Was there not enough demand? Did it take up too much time from technicians who are already stretched thin?

Given the long repair backlogs in the United States, it makes more sense to have service technicians focus on vehicle repairs rather than spending time wrapping cars.

Inventory Foundation Series

The Cybertruck Foundation Series is now available as an inventory vehicle in certain locations in the United States. That means you can pick up a Foundation-series truck with little to no delay.

Only a few trucks are currently in stock, but this will likely expand as Tesla continues to ramp production and begins to offer the non-Foundation Series trucks as inventory vehicles.

These inventory vehicles are only available in the United States. Canadian owners will still need to put down a deposit for a Foundation Series Cybertruck to get it soon.

Crossbars

Tesla has just announced it is offering a new set of crossbars for the Cybertruck. With a load rating of 200 lbs, it’s on par with roof racks for other trucks. These crossbars also come with mounting pads and quick releases. There are also slots for attaching ski racks, bike racks, or even cargo boxes, letting owners expand the truck's storage capacity.

Interestingly, the Foundation Series trucks can install the crossbars over the cabin or the truck bed, while the non-Foundation Series can only mount the crossbars over the truck bed. That isn’t the greatest news - because one of the best uses for these crossbars is protecting the cabin glass when you’ve got items like long wooden planks hanging over the roof of the truck. Maybe we’ll see more on this soon.

Update: It turns out that you can, in fact, install the crossbars anywhere on a non-Foundation series vehicle. You’ll just have to pay for an additional roof applique, according to Wes Morril, Lead Engineer of the Cybertruck Program.

Faster Charging

Tesla announced updated versions of the V4 Supercharger, with a more powerful electrical cabinet that can charge the Cybertruck at up to 500kW. That’s an insanely fast speed—nearly 1,300 mi/hr of charging. This will come as part of a future update for the Cybertruck and as V4 Supercharger stations begin to be deployed.

That’ll make the Cybertruck the fastest-charging Tesla - even with its enormous battery.

Tesla Unveils V4 Superchargers Capable of Charging at 500kW [VIDEO]

Not a Tesla App

Tesla has revealed its updated V4 Superchargers, which have a massive power increase and can charge vehicles at up to 500kW. The V4 Superchargers have been a work in progress. They were initially launched with a v3 cabinet, limiting their overall potential.

V3 and V4 Superchargers have been charging at 250kW for several years, but recently, Tesla started a public trial at some locations with Superchargers reaching power levels of 320kW. This speed bump out of the 250kW zone was our first indication that Tesla was looking to roll out improved charging speeds.

With these new V4 Supercharger cabinets, Tesla is ready to blow these numbers out of the water, however, not every car will be capable of charging at the new 500kW speeds. Fun fact: Tesla’s Superchargers first arrived with a charging speed of just 90kW.

V4 Supercharger Cabinet

The V4 Supercharger has been around for some time—it's the new one without a hole in the center. However, those were running with V3 or V3+ cabinets. Now, the V4 cabinet has arrived.

The V4 Supercharger cabinet knocks that 320kW V3+ right out of the park. It can put a massive 500kW into the Cybertruck—currently the only vehicle that can use that speed. And that 500kW works out to a blistering 1,300 mi/hr for the Cybertruck — nearly 2100 km/h of charge speed.

Part of these charging improvements come from the Cybertruck’s 800V system, so we can’t expect all these charging improvements to roll out to older vehicles. Instead, we can expect the upcoming Model Y Juniper Refresh to likely also arrive with an 800V system, with all the experience and knowledge Tesla has gained from the first year of the Cybertruck.

If the new Model Y achieves charging speeds comparable to the Cybertruck, it could deliver remarkably fast charging times. Being lighter and more efficient than the Cybertruck, the Model Y could achieve a significantly higher miles-per-hour charge rate at the same 500kW charging speed.

These new V4 chargers will support vehicles with 400-volt and up to 1,000-volt vehicle architectures, so people with non-Tesla EVs that support 1,000 volts will also see some drastic charging improvements.

V4 Megacharger

In its brief video, Tesla also showed off the updated V4 Megacharger dedicated to the Tesla Semi. The new MCS system can pull up to 1.2 Megawatts, which is 1,200 KW of pure power via the MCS connector for the Tesla Semi and its massive battery pack.

This upgrade for the Semi is going to be big, making it a prime option for companies looking to do short—and medium-haul trucking—nearly 90% of the trucking in North America.

V4 Supercharger Rollout

The rollout of V4 Superchargers will start early next year, with the first sites already undergoing permitting. Most interestingly, Tesla’s new V4 cabinet has also reduced the complexity of the Superchargers even further.

The V4 cabinet powers 8 posts, which is 2x more than the V3 cabinet. A smaller footprint and less complexity mean faster installations, which means more V4 sites faster.

These new Superchargers have the potential to ease congestion and help eliminate the negative perceptions of slow EV charging.
