It is coming.
Tesla makes a semi truck, and several other brands are breaking into the market. Probably not what you're interested in, but the EVs are far more than just little golf carts.
The Chevy Silverado Work Truck was supposed to come with a 20,000 lb towing variety, but it hasn't made it to the market yet. I'm hoping perhaps spring of 2025.

Smith Newton has been making small box trucks for about a decade now.
Smith Electric Vehicles manufactures and markets zero-emission commercial electric vehicles that are designed to be a superior alternative to traditional diesel trucks and provide a lower total cost of ownership.

Some of the older Smith Newtons are now making it onto the secondary market.
I think a few other brands are also working on the small truck market.
