Does it make sense to use hydro, coal, natural gas or nuclear?

Thanks for the welcome. I’ll pop in from time to time. We have anchored on our next RV but won’t be buying till the new year so we feel a little funny posting on an RV board without an RV. Looks like we are going with a T@B 400 and towing with an EV SUV. Probably model Y or model X. Fellow in town has the model Y and T@B 400 combo and him and his wife are having a blast. And small enough to get on the smaller ferries that go to the smaller islands off Vancouver island. Some amazing hiking...assuming you don’t get eaten by a bear. :). We put in a reservation for a model X just in case as the waiting list is 8 months to get one. But the reality is we’ll probably just get the model Y. It’s going to be a big change from that pusher. :).
Cheers.

I can’t speak for other vehicles but certainly our present EV uses no where near those suggested numbers. Typically AC draws around an additional KW plus or minus. Think of a small 5000 btu Home Depot air conditioner mounted in a small space like a car. It doesn’t take long to turn it into a meat locker. If you are stuck in traffic for 8 hours and wanting to keep cool an EV is a great place to be. You might use 10 percent of an 80 KWh battery. Really, running AC is not a big deal. The car figures it out and calculates your required charging stop and location accordingly.
Cold? It depends. If your EV has a heat pump it’s not too bad down to a certain point before resistance heat kicks in. If you have an older EV that only had resistance heat you can lose a third or more of your range. Either way, the car figures it out and calculates your charging stop and location accordingly.
Of course, as always, analyze your own needs and see if it’s right for you. For our needs and performance expectation gas vehicles have lots of disadvantages and no advantages so it’s an easy decision. But others with different needs and expectations may be better suited to gas vehicles.
Can’t speak to towing as we have no experience towing with an EV.
I’m not sure if the OP was planning on towing to his sons house, although I didn’t get that impression.
Cheers.
Welcome back @Reisender and your invaluable real-life knowledge about EV's and charging.
As opposed to those "no it can't" party-poopers theorists, lol.
Ah yeah, I repeat. I have orders for both F150 Lightning and Cybertruck. And if I can get 150 miles between re-charging, I'll will be plenty happy as this is my stops anyways for lunch and bathroom breaks.
I'm into RVing for light and easy travels and not to accumulate mileage (no rewards for that).

I think that during a transition period you will see some campgrounds putting in 250kw chargers for electric trucks with separate charging fees, probably near the main power feed to the campground. Getting power to all of the campsites will take time and money but private campgrounds will respond to demand. Sadly, if history foretells the future, government campgrounds will be the last to upgrade their infrastructure.
We really need to let the National Park Service set their own fees and manage their own budgets so that they can expand to meet demand.

What if I carried my 200lb, 7200W, 240V/30A generator in the truck bed. Taking that same 350 mile trip, and say a realistic distance is 250 miles per charge. Let's say I travel 200 miles and stop at an out of the way location to take a lunch break. Out of the way meaning generator noise doesn't offend anyone. How long will I need to recharge at 7200W before I can reliably make the last 150 miles?
Ford hasn't officially listed the battery size but based on charging estimates from Ford, it's around 150kwh of usable battery bank.
That's about 2 miles per kwh to get 300 mile range. A 7.2kw generator running for an hour might add 14miles (might be a little less depending on efficiency). This presumes the generator is rated for 7.2kw continuous output and the onboard charger won't be limited to some lower charging rate.
So if you crank up the generator and plug it in just before pulling out of the driveway...assuming you are running at 65mph, 350miles will take 5.4 hours. Assuming the generator is in the back running the whole time at max output, that will give you the 300mile battery range plus an extra 75miles from the generator for a total of 375mile range...ie: you have 25 miles left when you arrive.
There are probably some errors due to efficiency losses, so figure you will be limping in on the proverbial fumes. Keep in mind 7.2kw is roughly 10hp. A full size pickup at freeway speeds is likely drawing 60-80hp to keep up the speed.
Umm, I think the biggest error in your calculation is the fact that EVs can't be driven and charged at the same time....

I dont/will not own one, but even Tesla fans admit the range suffers horribly. Teslarati article and this was a less than 5000 lb boat. A travel trailer, due to the frontal wind resistance will be considerably worse.
As an urban, maybe even suburban, grocery getter, enjoy your tesla or other EV, but to work for what folks do for RV'ing they have a long way to go.
