Depending on how your delivery business is structured (customer density, and what type of driver's license your drivers have) your efficiency may be constrained by (a) driving time/distance, (b) vehicle legal curb weight, (c) vehicle reloading time or (d) at-customer delivery time.
If your company is constrained by (a), (b) or (c) current electric vans will make that limiting factor worse. Post offices are mostly constrained by (d) which makes it easier for them to deploy electric vehicles.
None of these problems are insurmountable, but current electric trucks aren't drop-in replacements for diesel trucks.
