In light duty trucks EV can work. Heavy duty EV trucks carrying heavy loads are a long way off. Range, charge time, heavy batteries etc are all obstacles. They are advancing DPF and emissions controls. The next big thing is likely a electrically heated DPF which will reduce the fuel economy penalty of current DPF systems. I think we will see diesel hydrid trucks before we see full EV superduty trucks.
The main issue of this thread was off road parts being harder to come by. They are still available from many sources outside of the US now as they are out of EPAs jurisdiction. I do still see the EPA busting shops that are installing off road parts on street legal trucks. Many of the large tuners still here in the US are switching to offering only emmissions friendly parts and tuning. It takes refined tuning to make more power and preventing DPF failure.

And it does take very sophisticated tuning to make a truck with emissions components run reliably. I don't think we are there yet.
If it can ever get past R&D ducted fuel injection for diesels seems to be very promising.
I was thinking about the issue with FCA or Fiat (?) getting in trouble for making the trucks run one way on the road and a different way when doing state mandated emissions testing so that the vehicles will pass. This may have been an issue with the half ton diesels only. Since this thread did get testy in some parts, I am not trying to be an a$% just curious about your perspective of how deleted vs emissions intact trucks smell.
As far as the OP's original issue. We will continue to have issues with sourcing off road parts in the US.

Clean smell? Oh man, my 2016 Cummins was the only truck I've ever had to turn off if I was going to be working around the tailgate or hooking up my trailer. The "clean" exhaust was absolutely disgusting and left me gasping for breath....it feels like trying to breathe in the vacuum of space, but with a noxious smell that burns my nose and singes my sinuses. I could not breathe around it. I can only imagine it being similar to someone with severe asthma going through an asthma attack, desperately grabbing for their inhaler...
On the other hand, I can breathe normally all day long around a pre-emissions truck. I really enjoy the smell.
