I would suggest there are 4 kinds:

1. People who need them for work. 2. People who need to carry bulky loads 3. People who need to tow. 4. People who buy them for some form of self-expression.

The only real use case for electric trucks, imho, is construction site supervisors who do most around-town driving but may occasionally need to haul stuff. Their towing range is absolutely abysmal (F150 Lightning range dropped to about 90 miles when towing a moderate trailer!).
