The huge cables needed to carry power from the trailer batteries to the tractor would add too much weight and expense. The trailer itself would need to be heavier to support the batteries. Keeping the batteries in one place—on the tractor—would be much simpler and more cost effective.
For the purpose these will be used for (delivering battery packs up and down hill to start), I do not see a range issue.
Tesla will be using these trucks themselves first to deliver battery packs instead of renting trucks etc...
As these trucks roll out to others infrastructure will be greatly improved. truck stops will most likely have chargers.
