easy to install and had me back out camping in perfect fit for 1999 rockwood this was an easy install that worked as advertised four stars good quality priced right three stars very easy to replace it was the wrong size it needed to be 1412 great easy replacement it was so easy not the companys fault but by the time product works well gray water help four stars four stars does what it is supposed to and looks much better with my airstream than the plastic ones well made with some limitations and none of them are great but ive had my alum supports for the it is durable its easy to use and it does the job as expected two thumbs up
