I think the more important reasons are to prevent the groceries from sliding around in the bed and to protect them from the sun and precipitation.

Another reason is to avoid letting the inside of the bed get scratched. I lived in Texas for a while, and people were that fussy about their trucks.

So true! My Ram 1500 was purchased to pull our travel trailer. It has the tow package and is factory raised up some. I'm kind of old, so I keep a three-step ladder in the bed so I can easily climb into it.

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.)

I just made up a name. I know Rebel is a model that’s hilariously large. Don’t know about others.

Yes, the RAM Rampage is comparable to a Ford Maverick which is a unibody vehicle with a truck bed.

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.

That’s what one would expect, but in some parts of the US it’s not uncommon to see dilapidated houses with a shiny tricked out F-150 that’s never worked a day in its life sitting out in the parking lot…

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

I grew up in a suburb of Detroit, and when I went back to visit the family home a few years ago, every street was parked up on both sides with giant vehicles. It was a sight to behold.

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.

some guy left a few hundred pounds of steel in the loading area of my workshop for stupid reasons. maybe about $80 worth in scrap. he kept coming by and claiming someone was going to pick up it up, and getting really threatening about us stealing the value from him. the scrap yard is 200 ft away. he drives a big jacked up truck. after a couple weeks of this I'm like 'look, I'll cut it down, and we can throw it in that truck of yours and you can roll 200ft down the road and we'll be done with it'. he was incensed, his bed liner would get all scratched up.

after that I dragged it out onto the curb for the meth addicts to sell.
