It has seemed to me, having watched the videos of the R1T (truck) in action, that it has significant off-road capabilities, just as would be required in an agricultural or construction site setting. Ford pickup trucks are great, but the savings expected of one that is electric would be the time it takes to refuel, versus unattended battery charging, reduced maintenance and possible energy savings.
Historically, by the way, electric vehicles were widely used in the early part of the 20th century to deliver ice in cities like New York. There is, of course, discussion currently that Amazon will be using electric delivery trucks.
All the previously described “bare bones” option requirements would be attractive for these settings. I would expect to see electric technology enter in the usage of farm tractors as well, due to superior torque and better handling when tilling fields. That of course would come much later and could be available in other mechanized farm equipment, possibly developed by companies other than Rivian. However Rivian’s skateboard design was discussed elsewhere and of interest to Ford for incorporation in their EV lines. This, again, would be desirable due to better torque, reduced maintenance and fuel savings that could come from generators driven by the forces of nature, where available, and stored in new generations of high energy density batteries.
