Fully loaded truck vs empty truck?
Yep
How much does the rig with batteries weigh compared to a diesel truck with a full load of fuel.
Also don’t forget that an electric rig weighs the same when discharged as when it is fully charged.
A diesel truck weighs less and gets better fuel economy as it burns fuel. The electric truck takes as much energy to move itself when almost completely discharged as it does when fully charged.
And of course, a truck can only legally weigh so much when on the road. The more the weight of the battery the less load the truck can carry
