What makes some technical sense to me short-term are electric pickups, vans, and light trucks with about 100 km (62-mile) of battery range when lightly loaded, but backed by a range extender sized to handle the “towing” power demands. There seems to be interest in this approach in Europe around large cities.
Even this makes most sense in US only for those who use their trucks mostly for private transportation and tow for recreational needs occasionally. Battery capacity, cost and weight are limited, but adds cost and weight of range extender.
Ford has smaller Transit Custom van like that in Europe, and I’d consider the full-size Transit for a camper if built and sold here. The hybrid power train could support camping needs extremely well if Ford allows it.
