The data indicate otherwise. Have you considered an actual technical explanation as to why what you claim might be so? Compare the effects of changing loads on ICEs and electric motors. I think you will find that the physics gives very good reasons for the effects on mileage and range to be similar and no reason for things to be the way you suggest.Yeah... except there is overwhelming testimony out there of ACTUAL EV truck owners who say differently.
If you fill a gas tank of an ICE truck... and tow something, you are not going to run out of gas in 90 miles. Not going to happen.
Yet, there are literally 100s of EV owners loudly complaining about losing way more mileage that the industry says they will get.
This is just one video.
I could easily post up 50 and more just like it
You have yet to make a comment on the effects of towed loads on ICE vehicles. Why is that?
