Clothes pinThis does work very well. I put a set on the ends of the gutters on both sides of my camper and they lasted about 4 years before the UV deteriorated them and they needed to be replaced. Never removed them during travel either. Held up fine to highway speeds. Extends the drip about 2" from the side of the camper so eliminates the black streaks under your gutters, even if your parked a little unlevel side to side.

Hope your travels are safe and the friendships made camping are lasting.
