That was the hope, but I stayed up far too late just putting the cab together. Kind of embarrassed at how many hours went into such a simple setup.
Sure wish I'd realized that I'd just be gluing paper over the entire thing anyways BEFORE I decided I needed to invert and reconstruct the boxes inside out.
I'll admit I was kinda hoping the costume included an enormous and unwieldy trailer of diaper-boxes.
