Unfortunately I also have about $20k "invested" in the wheelchair adaptations so trading for an EV won't fly. Otherwise I'd be sriously thinking about it. But even for us the EV range is an issue even just making a quick trip Tucson - Phoenix for lunch. About 100 miles each way.Very short drives are killer on fuel economy.
This sounds like the ideal application for a Transit EV.
JimA - You might be able to sell yours at a profit, and get an EV Transit at a discount because some dealers were forced to take them, even in low-adoption areas, and regardless of whether they have the skills to even explain how it works.
