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.
