I have a 2012 Cyclone 3010 HD which I have used twice with no major issues. However, this last time out I found a couple of black plastic squares shaped like a wedge on one size. They are about one inch square and about a half inch tall. Upon looking around my unit to see where they came from, I noticed there were others like them on the edges of the front and rear exterior doors. They appear to be mounted with contact cement and not very permanent, and others are about ready to fall off. They look as if they were there as a spacer for the door during construction. Does anyone know if my suspicions are correct and can they now be removed?
