Because of the poor gas mileage, I always wonder at why people drive these gas guzzlers as their main transport. But each to his own. (BTW, some claim safety, but it's probably fashion.)

The massive truck they likely meant would be a RAM 3500 HD super crew cab full size bed Cummins diesel dually rear axle with a vertical dual stainless steel smokestack exhaust kit for good measure. Which is essentially the largest truck you can get with a pickup bed from RAM, GM, or Ford; and they go for over $100,000 with options.

There are even larger monstrosities with pickup beds built on top of 550/5500/Class 5 truck chassis which are basically a Canyonero from He Simpsons in real life: https://www.elevationoffgrid.com/

My favorite derogatory term for a vehicle type is ‘hausfrauenpanzer’ which means ‘housewife tank’ in German, which is used for a large SUV in Germany, lol.

I think for some it’s an identity thing more than anything else.

They weren't all the most expensive trucks, and many were noticeably older. Things in our town went up and down with the cycle of the car industry.
