Hi Tim ,
Well, fair enough, (shoot, I forgot to reply to you directly, so, @Dioramartin )
I know we from across the ponds of the world call things by different names. For the sake of what I’m talking about, the fender is the part of the vehicle body that covers the top side of the tire/tyre wheel, whereas the bumper, is the big piece or pieces of steel that separate the front and or back of the vehicle from whatever is in front of, or behind it. On this truck, the front bumper is pretty cool - not just a plate or channel, but fabricated triangular shape that projects out from the chassis.
Regarding the pictures, wheels, and base - you’re eye is basically right. They are just dryfit on the spindles and axles, and only loosely held on, so they tend to rest as they see fit, whether we like it or not - 
Cheers
Nick
