The dealer would have sold you a super cheap hose. You are better off. I bought the following hose which 5ft shorter than the one you are looking at but $15 cheaper. It depends on how much hose you will need. They are good hoses and I have never had an issue. They come with covers for when they are in storage. This is the best I have had and I have been buying them for over 15 years.
