So I was never able to catch a picture of left side catering or catch a picture of the Delta catering, as I was in a different terminal, but I have made a quick (key word "quick") sketch of it. As it is a very simple design. Maybe someone else will be able to catch a picture of it.
The picture is exactly what they had in the center of the vehicle and on the door. I could make it myself though even reading the manuals I've had trouble making some. Thanks.
