Electricity assuredly is NOT everywhere. There are large swaths of the US where you will be very far from a plug. Also, it takes an impractical amount of time to charge an EV pickup truck on anything other than a fast charger.
We are not anywhere near where the infrastructure is ready for EV pickup trucks to be practical for a large number of people that currently need them. We may get there some day, but not for decades without a huge breakthrough in battery charging technology or manhattan project level investment in charging infrastructure.
220V 50 amps electricity is effectively everywhere. Those large swaths of the country with nothing in them are also places where there’s generally far less traffic.
Where do most pickup trucks get driven in the USA? I'd guess it's not in the middle of nowhere, at least that wasn't my impression when visiting the USA.
From a sheer volume perspective you're probably correct, but if you venture out into the less densely populated areas of the country (with more sparse/nonexistent infrastructure) you're more likely to see a truck on a given vehicle encounter. These are the places where electric is a non-starter.
You don't have to venture far from the major East Coast cities to get to "nowhere." For example, there are plenty of remote areas in WV (Canaan Valley, Dolly Sods, etc).
If you go camping in those areas, you have to make a 3 hour charging detour on the return leg. There are no public chargers in the nearest towns or on the main road into the area.
If you rent a cabin, you can probably run a charger out the window. Rent a condo at the ski lodge? Not sure, they didn't have chargers a few years ago, but might toady.
I camp in the Appalachians regularly, from DC. There a quite a few spots I can't get to without a 3 hour charging detour (2 hours charge time, 1 hour road detour to get to EV station) on the return leg. And that's for areas that are only 3-4 hours away (one direction). [this was using ABRP and a mid-range Riviant R1T]
