I also have a full-size pickup with no professional necessity for it. I'm just a home-owner who does all of his own maintenance and repairs. I've entertained a couple of times going to a smaller pickup, even tried to order a Ford Maverick when they came out, but have been very glad more than once that I've stuck to full-size. Recently tore down the deck on the back of my house and built a new one, it would have taken at least twice as many trips with a smaller truck, and couldn't have done it at all (by myself) with a car.
I travel a lot for work, so have seen quite a few cyber trucks. Recently in Tennessee I saw one pulling a decent-size camper at a truck stop, so i asked the owner how the camper affected his range. All he said was "Range? What range?". I'm guessing he wasn't thrilled.
