Considering everyone tends to point out the Achilles heel of EV trucks is the high kerb weight limiting the tonnage of useful cargo, I find it really funny that their premier touted customer is Frito-Lay, whose products are universally referred to as bags of air.
Did a quick search. Diesel Semis' curb weight ranges b/w 10000lbs-25000lbs. The 10000lbs one may not be comparable in performance/range to Tesla Semi so keep that in mind.
Tesla Semi based on the estimate in the article, is about 27000lbs.
