Now I get why the gas powered Hilux has changed. Emissions standards have changed. Fuel efficiency is more important. Modern cars are full of computers and microcontrollers. But an EV is relatively simple. It's one of the big advantages. Yes you have an OS and it's not just turning the ignition but the drive system itself is fairly simple, the thing that turns battery power into movement (compared to ICEs). No moving parts (in the engine), basically.
You could absolutely make a small EV utility truck. Remember that part of the reason why people were excited about the Cybertruck when it was announced was the price point (~$35k). Of course it turned out to be 3 times that.
Look at what BYD is doing [1]. Now these are PHEVs rather than pure EVs. Other automakers are making smaller pure EV trucks.
