He’s probably right, but the 600 mile range would come at a cost to price, weight and handling........................
Interestingly, one thing people hoping to get a F-150 Lightning EV are looking forward to is the heavy batteries in the extended range version hopefully increasing handling. The idea is that all of that extra weight at the bottom of the truck (where the batteries will be) will lower the center of gravity. If they're right it'll be the first truck that looks like a truck (the F-150 Lightning is shaped like a run-of-the-mill gas F-150) and handles like a car around curves.
