Airport Fire Truck with moving ladder and spinning wheels

This airport fire truck model features a moving ladder via a ball and socket joint, as well as spinning wheels. It can be printed at just about any scale, but at very small scales the wheels cease to function. If you happen to have a big enough 3d printer, and you want to print this, all I ask of you, is that consider printing one as big as one of the large, classic metal Tonka Trucks. I just want to see how it turns out. Thank you for taking a look at my model.
