For most of the Australian public- you can't even DRIVE one of those 'trucks' legally (even unloaded) basically anything over a F150/Ram1500 is a nogo without a truck licence... and if you did and were caught (and you would be the first time you were pulled over at an RBT) then you are classified as an unlicenced driver (even if you have a valid car licence- you do not have a valid truck licence...)- 3 months licence suspension, and well over a grand in fines (and god help you if you are involved in an accident!!!)
So its a bit pointless even trying to sell them- here your rego costs go WAAAY up, they cost a small fortune (as in more than many peoples houses) to buy new (if you can even find one- Ford don't sell them in Australia, Dodge only sell the 1500 and the Chevvy isnt sold here either) when you could buy the Euro/Japanese trucks for quarter of the price, and get far better mileage with their diesels than the US 'monster trucks' (which use more diesel than my 8 tonner Mercedes tiltray does!!!)
An EV version is already available (several in fact)- theres the ECanter I showed before, the Hyundai Mighty, Isuzu ELF, the JAC N series, LDV EDeliver all are capable of towing 4.5 tonnes or more, some up to 9 tonnes if you have a MR truck licence all with 300-400km range and fast DC charging and cost less than the US 'trucks' anyway...
So your arguments may apply in the US- but not anywhere else... (and the US is well behind on EV uptake compared to many other countries, even here in Australia, they are taking off in a big way...)
