Roll around work tables are nice to have and I move mine out for nice view of the rice fields and mountains when I am working. I was going to cover the top box with a door but in the end just went with plywood with hardwood edging. The inside is supported by 2 x 2 hardwood so I can store long balsa tucked all the way back. The holes in the box make a nice place for parts and tools as well. This is my 73 inch J-3 Cub right after I brought it home from the garage sale purchase getting sized up.
