No these are modified. Last time I saw a vehicle like that it was a Mormon family out camping with their 17 kids

Edit: honestly if you’ve got a giant family and you’re basically a half a busload of people everyplace you go, that’s pretty much the ideal best use case for a private car.

Same with this picture — if somebody felt the need to pay $$$$$ for extending the truck, they’re probably actually using that space for something productive and not just driving it around empty. I’m way more mad about the incredible waste of every suburban individual having their own heavy duty cargo hauler for daily chores that don’t need it, then I am about modified special-purpose vehicles doing a job.

No car manufacturer mass produces a chassis like that. That's an unholy marriage of a suburban and an F250 super duty.
