It’s a Tesla thing if you’re trying to do calculations for a specific model. Getting it wrong can get you stuck or worse. For CT it’s not a good idea to assume 400 Wh/mi in a scenario like the OP described.
Not for extended boondocking. Once the propane is gone, it's gone. You will have to go back into town.
I'm surprised you're still confused on this. Even 1000W worth of solar panels and a compatible battery generator is going counteract the certainty of phantom drain and add miles of range every sunny day it's used to charge the EV. In otherwords, you can camp indefinitely, as long as you keep getting mostly sunny days, which is the reality in many popular camping areas in Utah, Colorado, Arizona, New Mexico, etc. That is not the case with propane or diesel, eventually your source of fuel runs out. And I know the sound of a generator running would negate the reason many people like to boondock in the first place.
This is an example of trying to be right. Now let’s see how many Cybertruck owners are realistically going to take their vehicle and vanish into the “boondocks” for a longer than a few weeks? If this is a real worry why not just buy a ICE vehicle and never need to worry about charging? Some of them can go 700 miles on a tank of gas! Hell why even take a vehicle at all?
“As long as you keep getting mostly sunny days?”
Best battery for this would be power wall! Or Anker x whatever
Sorry, that often happen when the usual suspects whose past time and actually source of joy is in pissing contests. Try saying today is Tuesday and someone will butt in to contradict that.
Actually on this concept, I've always wondered why we don't have turbines in urinals, because for all those bars where people are drinking and they go and pee, we could capture that energy into a battery that can power the urinals auto flush or something like that. I wonder why we don't do that.
I like the idea of driving the sun, but...last I heard was you can get about 15 miles worth of charge per day from panels. You'd have to sit around for 10 days to get an extra 150 miles. Not sure what you mean about getting charge back into the truck at night. From charging on site?
Why must you prove again that you didn't read my first post? Or the post you called optimistic?
Not only are you proving you didn't read my posts, you haven't posted any actual numbers.
I don't know where you're getting your numbers, but personally, when I'm around campgrounds, I'm not driving at freeway speeds. With an EV, that means you do better than EPA.
15 miles is 15 miles. That's a long way in one day of sun. It would take a long time to walk 15 miles and you couldn't bring all your stuff with you. You're not going to drive across the country with this, but for extended boondocking it can help you get back out. The usual problem with extended boondocking in an EV is your range gradually disappears with slow but predictable phantom drain. That can be a problem if you used 1/2 your range to get in, and you need almost 1/2 your range to get out. That's slim margins for phantom drain and estimation errors. You may or may not make it without adding some daily range from solar.
Do you realize that the phantom drain/efficiency when charging at 120V @12A is about 600W of loss?15 miles is 15 miles. That's a long way in one day of sun.

For those more interested in doing this than arguing, I'll show you a system that can help add range to your Cybertruck as you boondock for extended periods. In the Dual Motor Cybertruck you will need about 3,870 Wh per day (not including charging losses, transmission losses and phantom drain) to add 10 miles of EPA range per day. Generously assuming you will need to produce 30% more electricity to account for losses, you would need 5,031 Wh/day of solar production.
To this 1200-watt, 6 panel system, it would be necessary to add two 3 into 1 solar panel plug adapters and a bonding ground plug (to fool the Cybertruck that the Jackery outlet is grounded) for a total system cost of around $4,600. Some solar panel extension cords could be convenient too, but I haven't included those.
These six folding solar panels will stack into a space only 9.5 inches tall, and 24"x21" (WxD). The solar panels each weigh 17.5 lbs. The battery generator is 10.5"x12"x15" and weighs 43 lbs. for a total system weight under 150 lbs, including the solar panels. This will have near zero impact on range, compared to how much it can add on the first day.
The 6 panels in this system are 200 Watts each for a total rating of 1200 watts. However, solar panels rarely produce their full rated output. Under full sun, you should be able to conservatively get in the neighborhood of 900-1000 wh (or almost a kWh for every hour of full sun). That means in 5 to 6 hours of direct sun, they can produce more than the 5,031 Wh needed to end up with 3,870 Wh (conservatively) in the EV after accounting for all losses. That's 10 miles of EPA range in a Dual Motor. This assumes Tesla optimizes the software to bring Cybertrucks phantom drain into line with their other EVs (which is a good assumption, I think).
Also, the panels will produce electricity in the early morning hours and late afternoon hours, albeit at a lower rate, this can be used each day too, by charging up the 2.1 kWh battery generator. That production is in addition to the 5,031 Wh calculated for production during the peak 5-6 hours of the day, when the vehicle is actually charging.
