Paper folding dump truck for kids. Art project.?

Question

I have an assignment that requires me to "build" a dump truck for kids that would be a folding type of thing and would be given away as a promotional item. It needs to be simple so that the kid, but most likely the parent, will put it together. Minimal tape or glue. Any suggestions? Oh, I'll have to design something on this truck so it'll be printed on card stock weight of paper. Thanks much!
