This is actually better, because the extended cab means a short bed which cannot accommodate the long channels in the truck. If it's sticking out the back, it's a hazard on the road. It could go in the bed and strap the other end to the roof, but then you have a horn sticking up that can catch overhanging branches and whatnot. If it isn't strapped securely, it could slide off to one side where it becomes a hazard again.
I agree, this person probably doesn't need a pickup truck. But they have the materials loaded correctly.
4 x 4 refers to the power delivery to all four wheels, as compared to FWD, RWD, or AWD. It's not a brand or model of truck. You can see the model badge on the side, which says it is a RAM 1500 Warlock with a Crew Cab and a 5'7" box. RAM is the make, which is owned by Dodge, and 1500 is the model, which is a light duty half-ton truck comparable to an Ford F150, Chevy Silverado, GMC Sierra, or Toyota Tundra. The Crew Cab means a full size back seat at the expense of a shorter bed. The Warlock trim level is new for 2025, and implies comfort and style over function.
So you're correct that this is probably more of a fashion accessory than a work vehicle, but it's not because of the drivetrain.
