MOKE 2XS 

Here you can see details of the trailer construction.
The body is all out of wood, so it is kept well covered from the weather.

The rear tailgat is easily removable.

The front panel can also be removed and then the trailer can hold 4' x 8' sheets of plywood.

The trailer will handle 1.5 cubic yards of soil, and the Moke has no problem pulling it.
