Okay, actually for city deliveries with low speed limits and lots of stops plus traffic lights (regenerative braking instead of wasted gas while idling!) 120 miles is not as limiting.

I could realistically assume that you're driving only 2/3 of the time at average speed of 30 mph... and that comes out at just 240 miles per a full day, and you could get a partial charge during e.g. lunch break, so if the battery was just a bit larger, then it's actually feasible.

That sounds about right. My experience with a Tesla is that city driving is somewhat more efficient than highway driving, typically. The constant starts and stops still cost you, but not as much, and the lower speeds make up for that loss. I don't know how how true that would be of trucks, but I'd guess it would be similar.

With good DC charging, you should be able to count on adding 50% of your battery over a 30-minute lunch break, so if you do 240 miles in a day, your battery pack would need to be able to handle 160 city miles. Less if your truck is idle more or if it could charge more.
