Until the late 1970s, they were put only at the end of the trailer.

For the first time, he looked out the window of the trailer.

The back of the white trailer looked much like the front.

A man I did not know ran forward from the open door of the trailer.

A second later she saw it, standing hard against one end of the trailer.

King didn't head to the front door; instead, he went around to the side of the trailer.

I got down off the steps and went around the other side of the trailer to the front door.

He stood up, but to my relief moved to the other end of the trailer.

She went to the other side of the trailer, and looked out the opposite window.

The interior of the trailer is a far different story, however.
