Yeah, I'm also gonna need some sort of evidence for that claim. Sure there are vehicles that are wide but that's by no means the standard. Hell, I bet the truck in the picture isn't even much more than 6 foot wide. A modern Corolla is about 6 foot wide.
Not who you were talking to, but out of curiosity I googled. Obviously this differs based on year, but current model Silverados seem to be 75-80" (1.9m-2m) with Corollas averaging 70” (1.8m), neither including mirrors I think and mirrors on these type of trucks are often extended.
I looked up the same thing actually and the Corolla dimensions included the mirrors. So, I would assume the same for the truck, though that could obviously be wider if the they have extended mirrors because they tow frequently.
Perhaps it's because the mirrors on trucks are so frequently modified. So, it's more meaningful to tell you the width minus mirrors rather than width with the mirrors that will get removed anyway. And the contrary being true of the Corolla of course.
I mean he doesn't owe me anything, strictly speaking. But he's the one making a claim. The burden of proof is on him.
Also, why did you write this comment? Just to be petty and spiteful? Think before posting useless and mean comments next time and then you might actually have something meaningful to contribute.
