From what I've read on EV forums, and in consideration of the physics at play, there's nearly no loss in range due to weight or gaining elevation, assuming the start and finish elevation are the same.

The extra power required to climb a grade is reclaimed when descending back down. Any excess speed that would otherwise be wasted in an ICE vehicle is instead recaptured at fairly high rates of efficiency.

Same with weight. Once the extra power is expended to bring it up to speed, no extra power is required, and it gets mostly recovered by regen when slowing back down.

Aerodynamics is nearly everything in an EV. That's what consumes the energy.

I expect Hersbird is correct about 1/3 the range when pulling something very aerodynamically dirty. The weight won't matter so much; only the shape.

The other range killer is cold temperatures. Some people see only 50-60% of their summertime range in the winter. Combine cold temps with a large trailer, and people could see 25% of the range they would otherwise get with no trailer in the summer.

All that said, I'd never intend to use an EV for long distance travel in the first place, so it's all moot for me. ICE is the appropriate tool for the long distance job for now. If I were a contractor needing a truck for local jobs, the CT would be a serious consideration for me.
