I agree with Leno on the performance aspects of electric motors over ICE vehicles. However, you cannot predict the demise of ICE vesicles on performance alone especially in a towing application. There will have to be major energy infrastructure and battery recharge enhancements done before BEV's become the dominant choice for most North Americans. BEV manufactures have a hand in batter charger enhancements, but they have no hand in the energy infrastructure nationwide.
The worst part about the energy infrastructure is that it is not owned by one entity. There are various different entities with different budgets, capabilities, and ideologies. The current infrastructure is fine for the small amount of people using BEV's(about 1-2% of US market share last I checked), but most areas aren't anywhere near being able to handle having 25% of vehicles being BEV's let alone a majority of them. Not only that, but it seems that most will not be ready for that kind of BEV market share anytime soon without a lot of money and man power to build the infrastructure it would require to make that much energy and distribute it to these chargers.
