I’m sure this idea isn’t new or as easy as it appears to someone like me with no truck / trailer / manufacturing experience, but-

Any chance of a cyber trailer with a battery of its own to mitigate range loss when towing? I could see it having a motor for regen as well, maybe less so for pushing. My thinking is the truck is easily smart enough to manage all that, but reliable connections and maybe a couple more cameras would be needed.

Then there’s cost, which may price it out of reach.

I tried searching ‘cyber trailer’ with no results and I’m new here so apologies if this idea was pitched already.
