My 2001
Scamp did not have a stripe so I ordered one from the factory and put it on. At the same time I suggested that they put the stripe on all the trailers from then on. I told them that the trailer looked tacky without the stripe on the door.
Now when I added the stripe on the door I also put it across the A/C vent which is next to the door.
I can't remember if it was 2002 or 2003 when they did in fact start putting the stripe on the door. It was somewhere in that time frame.
