I just happened to run across this image and thought I'd see what I could find. Now everything I'm saying is of course my own opinion.
Well this is definitely "Uncle Jakes Auto Salvage Yard", as the whole image that I cropped is nothing but cars pilled on top of each other. These cars, as I've stated before, look a lot like our cars 50 or 60 years ago; that's not to say that the cars they use now are more modern-looking. The car that really stood out for me was the one I labelled 57 Chevy, Desoto, or the first Bat-mobile.
Now getting back to the original subject of this topic: the fuel truck. Looking closely at this vehicle, I'm going to call it a tanker, but it's not a large one, like that which refuel aircraft, or deliver fuel to your gas station, I think it's actually a lot smaller, and if I we're to guess it's probably a small tanker for collecting oil from the engines, gearboxes, and transaxles or rear ends of all these junked vehicles. There appears to be a humanoid pouring what I think is old oil out of a container and into the top of the tank while seeming to be talking with a little humanoid in front of him. The driver of the tanker is in what I'm calling the chariot, only because it kinda looks like one. The driver is one of these rodent looking creatures, who has a rodent head, but a humanoid body. He's partially behind a windscreen that wraps around the sides and front of the chariot, and is actually facing toward the tank portion of the vehicle, or towards the right, because that's the way I think it's driven. The chariot is attached to the tanker portion through an articulating hinge point. Instead of the wheels turning to control the direction of the vehicle, the two pieces rotate and provide steering. If you look at the very front, or to the right of the tank, it appears there is a blade attached to the front, which could be used to flatten an area out or shove old cars around.
In this image there are also several other humanoids and creatures as well as
a lot of vehicles.
I've also included an image from my first ever topic in this form, which showed a similar vehicle with a gentleman driving it
sitting on the rear, and I believe it also used a two-part articulating steering system.
Take a look and see what you see
Vehicle similar to tanker, with a blade on front, but configured with some other equipment.
