Yes, towing is a big potential case for EREV. A 600 mile EV truck (300 when towing) would need a 250kWh+ battery pack.

An EREV version could get by with 50-100kWh, which is also a lot less weight to carry. And would give plenty of power for driving EV-only for shorter trips when not towing.

It would most likely be closer to the top of that than the bottom. The standard range Lightning has a 98 kWh battery. So you can see what I mean, the battery would only be slightly smaller. Slightly less expensive, and slightly lighter -- but remember that you also have to add back in the weight of the engine and generator.

Dropping 150kWh+ of battery weight needed to perform the job is not slightly smaller. The Silverado EV in max spec gets 500 miles of range, 250 when towing, and the battery pack weighs more than a Honda Civic.
