It's actually the same problem, ownership.

Who owns these batteries? Who owns these trucks? Who eats the cost on battery/truck degradation?

If I pull in with a battery that has 70% of it's original max capacity and get a brand new battery with 99% of it's capacity how do you fairly assess that value add to the truck?

Not seriously suggesting it, but what if the cab was easily swappable & the underlying truck was semi-standard? Still similar issues of ownership but at least truckers can bring their home with them, which seems to be important.

Silly yes. The 90's vision of the skateboard platform has stuck with me a lot. I'd imagined rolling lounges & other passenger vehicles cabins being a way to start decoupling the car, reducing the number of batteries motors and wheels that a town or city had to own in net. The usage cycle of trucks is a lot higher, and the swappability just for sale of switching batteries seems silly, but I couldn't help but see at least one of the core problems of swappability being solved by disaggregation the compartment from the rest here.

Seems like that might have the impact of doubling the money outlay for trucks, though it would work.
