Mini UPS man and his truck

I drew up the plans as my grandson started to walk while pushing somthing.Its made with 1×10 pine and put together with pocket screws. The wheels you see do not roll. I used 3 inch wooden wheels painted with rubber coating paint.I mounted 4 casters on the bottom the back two were apoxied so it would stay the same Direction as the front all corners were sanded.The rear of the truck is open so he can haul his toys.
