One thing that nobody seems
One thing that nobody seems to be commenting on is the unibody of the Rivan pickup truck. It’s my understanding that the bed is separated from the cab for a reason. As the Center of Gravity (CG) of the load changes due to the orientation of the bed relative to the terrain, the passengers in the cab are unaffected. With the unibody pickup, the passengers will definitely feel every curve or bump in the road. This is probably why Chevy’s El Camino and Ford’s Ranchero never made it as viable alternatives in the pickup market. If Tesla or Rivan want to entice the working pickup drivers into the EV market, they will need to decouple the cab from the bed.
