I was pushing back against the idea that the vehicles shouldn't exist and nobody should have them. I definitely seen some people who probably don't need it.
From my personal anecdotal experience, I know someone who lives out of a trailer and they are mobile all the time. It doesn't make sense to have a truck + sedan because they move around all the time. So instead they have one of those big trucks to lug a home trailer that they can drop off and then go do anything else they need in the area. Very specific niche case, probably would be ridiculed here if seen driving on the streets.
Someone else in the comment section somewhere gave some links that I can go over relating specifically to what you're saying.
I'm taking a look over them to help form an opinion. Haven't look at enough to really say any more on the matter yet. Although, I really don't think that some of the concerns brought up on the other side is completely off-base either.
