The Cybertruck body is 80"x224". If 100% of that area were 20% efficient solar panels and solar irradiance was 1kW/m², you could maximally generate 2.3 kWh * 12 hours of sun = 27.7 kWh/day / 380 Wh/mile = 73 miles of range per day

Propane portable generator does it cheaper, quicker, and lighter.
I was thinking of getting a multi/flex fuel option do you have a recommendation best paying for buck I appreciate your input on these kinds of things.

Very logical. I’m not suggesting the Cybertruck body be used exclusively as the surface area. I’m suggesting that having solar inputs would allow people to configure whatever portable array they want when parked. Currently, I carry 4 600w allpowers solar panels and a delta 3 pro generator that can accept them and deliver 240v charge via the mobile connector. For me that amounts to about 4-8 miles per hour when I’m camping depending on conditions. Real world experience, it has completely eliminated national park range anxiety for me and my family.
The generator is big and heavy though and would be unnecessary if there was an mppt input that could accept multiple portable panels wired in series to produce higher voltages.
What you’re saying about propane is completely true but that not only requires carrying the propane (concern here is space, not weight for me) but also requires that you be able to go somewhere that can refill propane. This eats up vacation time and requires driving somewhere thereby burning juice.
I also personally don’t think I would enjoy carrying a volatile pressurized gas in my recreational vehicle or combusting fuel of any kind at my campsite to refuel my car thereby defeating some of the purpose of a “clean” excursion in an EV, something I truly enjoy.
Completely sensible setup for your application! I was focused on non-stranding versus duration extension with body size as a guide for max collection. Collapsible deployable panels definitely boost collection ability.
Still trying to pick a trailer that works now that the extender is off the table (which at least helps from a payload point of view). Ember RV has a 1,200 watt solar option that is tempting, plus they have side solar input ports. I'll be checking into the All Power units. Thanks for the info!
All the trailers we're looking at have propane already, so no need for extra cylinders. Some toy haulers have generators and fuel tanks, but that sacrifices living space features...

I'm also toying with the idea of a upward wedge solar panel/ air deflector for towing and charging. Basically a ramp from the roof peak that mostly lines up with the trailer roof. Theoretically would help with both usage and generation.

I wonder if the solar wrap that was displayed at ces for the Cybertruck could be used to also cover the entirety of a trailer. You could even put that battery pack in the trailer so you so you don’t eat space in the bed.

Also, if you’re looking at portable panels, recently became Interested in this new product. I don’t have real word experience with it so can’t endorse it like the allpowers but it looks awesome in concept and specs.

Finally, here is a link to the panels I have been using.

Can typically be had for about $450-500 with prudent shopping.

Screenshot or people will question. I knew this would be the case especially with this turning out to be a low volume vehicle. I swear I see less of them in the wild now than last Fall.
Few CTs? We thought the same thing a few weeks ago when we took a 400+ mile day trip right through Austin and back without seeing a single CT on the road, anywhere. We thought we might see more around it's birth place but nada. Plenty of Tesla cars on the road but no trucks...it was sort of spooky but being the center of attention is not a foreign concept for the Claus's.

That's not an option without making the truck bigger, taller, or reducing the headroom.

The only way the CT gets more range is with additional energy density or to make the truck much smaller/aerodynamic (which will hurt towing).
This is nonsense. They could easily increase the size of the battery by 30% using same subframe.

Just watch …

I was addressing the unstrandable aspect (replacing the range extender). If infinite range is the goal (or setting up a remote site with recharge capabilities ?), go with solar.
My use case is getting truck + travel trailer the last X miles to a Supercharger.
I was addressing how silly of an idea driving around with propane canisters and generator for your unstrandable solution is.

So seriously how many bottles of propane would one use to generate a full charge from 10%?

Also no sacrifices from the trailer to use for truck. Using tanks from RV doesn't guarantee they would be there. Secondary tanks and generator. In truck bed or extra vented area for tanks? Can't put in trailer for safety reasons.

I guess people are just overall more happy with the EV cars and SUVs since they don't expect to use them for many things other than driving to and from and having some passengers.

Once you get into utility vehicles like trucks and work vans there are too many variables. One person might be happy just driving it around. Someone else might need to tow a space shuttle haha

Towing really calls out for a gas, diesel or propane range extender. A generator small enough to provide the cruising kW would be all that you need, let the main battery handle the load of acceleration or uphill travel. Could probably double the range with 5-6 gallons of fuel.

A+ observation and insight! I think you’ve really cracked the code. Seriously!

I’ve had no complaints about any of my other Tesla’s! NOT. ONE!

Again show me the number of propane tanks and the generator in the bed for the use with a nice picture. Till then it is all talk. Not doing. Some might think the idea just isn't practical as much as the people that suggest the idea. Is the idea put into practice? Doubt it.

We all need to post our disappointment on Elon's account on X! He needs to hear this one and not sweep this under the rug. Many bought the CT expecting this option. Yes expensive, yes takes room in the bed of the truck, but when you need it you need it! Tesla was so worried about the poor range on the release that they came out with this extended pack idea to NOT deter buyers! The R1-T MAX has a bigger battery, but with the extended pack, the CT has the bigger battery (more range). My guess is they did not get enough demand (nor for the CT itself) and they were going to lose money on it. So while it is business decision, the cost of burning your most loyal Tesla owners, will cost more over the long term as the buyers remorse will influence the next purchase decision, even on Optimus (as what else will Elon rug pull on us next AFTER you buy it?). Even for the CT owners that were not going to buy the extended battery, this should concern you as he is hurting the brand (and more CT potential buyers which will help save the CT) and you will not be exempt on something else you buy with Tesla (it is the process and "how" you do things that matters most, as it will rhyme/repeat again somewhere else at Tesla). The Tesla board is falling asleep at the wheel and needs to step in to protect the current owners (or class action lawyers will) and deliver on this promise or do something like offer a larger battery swap for $16k when they come out! Make it whole/right instead of burning your best customers! I can't believe they say "thank you for your understanding" with no explanation or understanding/acknowledgment of our loss as it influenced our decision to purchase the CT in the first place (we are financially buried in our Cybertucks while they got a free loan and lied to us?!).
I made and account and posted @Elonmusk and @Tesla.
Please share mine, repost, or post your own reply. We need to double down on this opportunity.

I don't see where I said the idea was easy or practical to execute in the Cybertruck post-design, I said it's what is needed in a vehicle intended for towing. I had a BMW i3 REX for a month or two as a loaner and it was a decent vehicle. Full EV drive train, the generator was just there to top up the battery charge. It was something like 60 miles of EV range and 60 miles added from the rex with 0.9 gallons of gas. Obviously the CT would need something a little beefier for both generation capabilities and capacity. At least one person has done something similar with a Model S, in theory it would be easier to recreate in the CT since the bed is outside the passenger cell. It would be interesting to see if somebody could commercialize such a unit for the Cybertruck, but I'm not sure there would be enough return on the investment.

Funny. I get torched on here every time I mention Tesla burning its best customers but this is not a one off. It’s a consistent trend.
I still support this company and its products but that’s the truth. Anybody getting involved with Tesla for the first time should be told that in my opinion.
I'm one of those who bought my Model 3 in 2018 with the expectation, based on Elon's statements, that I would be able to enroll it into a driverless taxi system and generate revenue with it by end of 2019. So I'm used to disappointment. That being said, the vehicles Tesla makes really are some of the best you can buy in the USA. We bought our Cybertruck end of 2023, and even with the failed promises and all the political fallout happening due to Elon's antics, we don't regret it our purchase. We may have made different decisions had we known what we do today, such as waiting and buying used instead, but we love our Tesla's. You are right though. People should not trust future promises made by Elon and Tesla at this point. Instead, just buy the vehicle based on what they get out of it today.

There is one type of utility vehicle where EV clearly makes sense and is now taking over from ICE: local delivery trucks. They charge in the yard overnight (when electricity is cheap), then make short stop-and-go trips all over town during the workday (but less than 150-200 miles total). No wasted fuel while idling, no side trips to the gas pump, no range issues, low maintenance. What's not to like?

For some people, the realization that EVs are truly practical will come when an electric UPS or Amazon van shows up at their door. Tesla skipped this market in favor of the Semi, but Amazon's order for 100,000 vans is helping to keep Rivian alive. Amazon drivers love them.

What was wrong with the physics? (Beyond asymmetrical axle loading)

Economically, a {$80k, $100, $120} + $16k vehicle that can get me to my destination is better than an {$80k, $100, $120} vehicle that can't, but it's situation dependent...
It added a lot of mass for minimal benefit (for the vast majority of truck users), the mass was well above the original center of gravityand further rearward than ideal from multiple perspectives.

Better to just have more DCFCers.
