I think the Scout Harvester will be much more efficient just based on the engine packaging graphic that Scout put out. The Ram is a full 3.6 liter(i believe) that takes up the entire frunk/engine bay area
As a local daily driver, full BEV is incredible. With current charging infrastructure, the harvester makes a lot of sense for my long trips within TX that often have 80+ mph highways(those speeds are no good for range!)
