I'm not sure what you're getting at with this. Here in Australia road trains haul 90 metric tons of grain and fertilizer all the time, that doesn't include the weight of the trailers.
Regardless, I'm not quite sure what you're trying to illustrate - your example of a "streamlined vehicle" undoubtedly consumes a lot more diesel than your example of a vehicle which is not streamlined. Isn't that antithetical?
Yes, but a "truck" with a 4 ton towing capacity obviously needs motors with more torque than those on a tesla.
As little as 5 to 10% on the highway, not particularly significant. Installing regenerative brakes on a trailer is a lot of additional cost and complexity.
