So much wasted energy from the source of generation to the EV motor.. Diesel engines are optimized for towing

We full time'd for a while towing a 40ft trailer with a diesel f250. While it is obviously not "efficient" relative to smaller rigs, it is way more efficient than living in a house and commuting daily even with an EV. This is one of those things I don't think people realize about "low carbon impact living" (or whatever you would want to call it), you likely get 80% there just by not heading/cooling a 2k sqft house all the time.

There really isn't.

US grid losses are about 5% [1] and charging loses another 10-15%, and the motors are at least 90% efficient.

Meanwhile, automotive diesel engines lose 60% straight out the exhaust pipe, and that's not counting the energy required to refine and transport the diesel.
