Slate, a customizable EV pickup for $20k
(electrek.co)
This is a most excellent place for technology news and articles.
It can probably tow more, usually 500 kg is like the bare minimum for American cars. Also us towing standards are a bit more strict. A car in the EU is rated to tow more than a car in the US, even if it's identical.
Even if it were 1000kg, that’s still way below what a truck would want to tow though.
Depends on the truck owner. It's not going to haul a boat, but it can probably do lumber (though the bed is kinda short and narrow), gardening stuff, and camping gear. That's basically what I'd want a truck for, plus the odd piece of furniture.
