Finishing the Front and Back

Here I got the front and back installed and started installing the corner beams for the sides.

He is a frequent visitor to the back yard where I work.

I propped up the back to make sure it is perpendicular to the floor.

The front window is set up.

One problem I ran into is that the utility trailer bed is not perfectly level. I had to raise the structure up and install shims to support the floor in places where it did not touch the bed of the utility trailer. For other parts of the floor I will drill small holes and insert short dowels.
