Product worked great for our 2005 Coleman Fleetwood Niagara Highlander. The old upper unit was no longer working and upon installing this unit, the top now goes up with ease! Glad to have bought this to fix a major issue. Only thing I wish I had was an install guide. The metal bracket of this product is actually welded to the inside of the large metal enclosure, which we were unaware of until install. We we’re still able to complete it in the end.

Every department I spoke with was kind generous and helpful I have said that to numerous people who have the Coleman pop ups and have referred you to many people.
