Is anyone actually using Cybertrucks for towing heavy loads? I'm under the impression it's mostly a recreational vehicle.

There are definitely pictures of people who try, one bloke put a towing crane thing in the bed of theirs: https://i.redd.it/32fsd1elmfvd1.jpeg

I think the stickers are the primary function, the crane is only to increase the liklyhood of someone photographing/sharing.

Really the primary practical use case for the Cybertruck right now is generating YouTube and TikTok content.

Not really because of the range issue I mentioned. I wanted it to tow my 9,000lb trailer.
