Hi Stan,
It is normal for a good reason. I assume that your trailer must be a "Twin"
bed layout, and the street side bed is positioned forward about one and a
half inches. The door header and jam are offset back about two inches,
enough such that the bi-fold door accordions properly when open. Actually
the header is further back than the jam on the curbside as when the door is
closed, it doesn't need the room on the curbside.
Bottom line, that's the way it is supposed to be...
