> but we don't know for sure because nobody builds the trucks we want.

Americans collectively purchase over 1 million trucks a year. They come in all kinds of different form factors from work truck with unpainted bumpers to 700HP supercharged dune runners, there are massive couches on wheels with interior made from saddle leather, to trucks pushing 1000ft-lbs to torque. There are EVs trucks with 400 miles of range and crossovers with the hatch turned into a tiny bed. There's even a Jeep Wranger with a bed (Gladiator).

If there's a significant market for a truck niche, it's covered. Trucks are far and away the most diverse segment of the US auto market. If manufactures killed of the truck you want, it's because they apparently can't find 1,999 other people to buy that trim.
