As far as people in the southwest "...running the A/C full blast" I promise you we can relate here in the southeast with our 90+ temps and high humidity. That's part of my math on expecting the miles per kWh to be 10% less than the advertised performance, much like buying a gas car. At least, that's what I experience compared to driving in the winter months. (For the record, that's also not getting into a lower performance when loading it with cargo, since I was using numbers for gas truck vs EV truck, not cars. That's a whole 'nuther ball of wax, but I use my truck like that maybe only 1% or 2% of the time without counting throwing grungy but light stuff in the back like a lawnmower or taking out my church's trash. If I toted heavy cargo a lot for long distances I'd be really worried about range per charge.)
I just flew in to KC and waiting on an incoming flight to take it to Philly.
