After you've accelerated the truck to highway speed, the weight only matters due to friction. The friction and aero costs are large enough that the acceleration cost doesn't dominate.

All these assume flat terrain. As soon as you start adding hills things look completely different. That's the one reason why I think e-trucks make sense, the ease of regeneration rather than burning off the momentum as heat.
