Well, another thing that's nice about Edison Motors is that they're the Engineers, Mechanics and End Users for the kits. It all started because they wanted a Tesla Semi Truck to try for their logging company, but got snubbed by Tesla. It should have much higher usability then a truck designed by someone who's never driven a truck before.

This isn't like a Prius where the Engine, Electric Motor and Tires are all connected mechanically at some point. The Diesel/Generator unit is only connected to the E-Axle via electrician power. Because the company supported open standards and open documentation, you could just get the e-axle, ESC, and battery pack and build a pure EV around it. They need to focus on a simple product line with the broadest use cases for starting though, so I'm not surprised they aren't talking about pure EV trucks.

There's also strong community and wealth of information on swapping EV guts into older cars. You get the benefits of EV without the spyware and info-distractions. These are all custom jobs though, so a cost estimate is impossible. Deboss has a very interesting EV project going on right now. Edison says the total cost of their kits should be around 1/3 to 1/2 the cost of a new truck

I have an old Scottsdale truck I'm eyeing for a Edison conversion. The juxtaposition of a modern diesel/EV hybrid drive train combined with an 80's square body truck with manual crank windows it too irresistible. All running on biodiesel as well.
