The Danish style cargo box is almost complete. I cut it out the other day, then finally assembled it today. Lots of glue and staples.
The box is 33-1/2" long (84 cm), 24-1/2" wide (62 cm), 20" high in the rear (50 cm), and 14.4" high in the front (36 cm) ... so the base is 84 cm long and 62 cm wide.
Next I need to tweak the metal cargo base just a bit and build the steering ...
