Bought this cover brand new. This is what our towing cover looked like on the inside after a trip of about 500 miles. It marked the caravan so badly that it took ages to remove the black marks. We now have a Specialised Elite and no issues 1000's of miles later.
That's the part of the cover which wasn't suitable for the shape of the Sprite. It kept coming out from behind the main panel. Now I think about it, I'm sure I had some marks left behind from this cover. Like I've said before, I was loaned the generic cover by ProTec, as the Towing Jacket had not been made.
