The F-450 weighed in at a whopping 5,240 pounds, though that's only 593 pounds more than a Model S P85. Greg says that the weight savings from the factory 7.3-liter diesel and its transmission were around 100 pounds, meaning that the overall weight increase was only 493 pounds. Moreover, because the battery box was fabricated to utilize the factory mounting points, the truck's overall weight characteristics should remain fairly close to stock.

Greg doesn't mention overall range, but it's worth noting that similar battery configurations in the Model S net around 265 miles, though we're sure that's at least somewhat sapped by the 500 pounds of added weight, age of battery modules, and the fact that the F-450 shares aerodynamic characteristics with that of a brick.

The interior of the vehicle was also modified. Greg refers to the large blank dashboard as a "pallet" for digital and analog gauges, though most of the functionality takes place via a centrally mounted EVControls T-1C Controller, a $3,500 piece of hardware which interfaces with the electric motor, power inverter, brake lights, and other components to ensure smooth operation. The interior was also fitted with sound dampening to mask road noise otherwise covered by the truck's diesel powerplant.

If you're interested in a more technical walkthrough of the truck's functionality, Greg has recorded a number of in-depth videos on how everything works, including the one below:
