Received during recent tropical storm, so construction not complete yet, but a few issues & suggestions. 1. the instructions are absurd- illustrations deceptive. A few written instructions would help. 2. when covering piping, reduce stress level & use silicone spray on pipe first. 3. pipes 800178 + 800179 Do Not go in front & back flaps, but the sides. Diagram is confusing. Once up & exposed to elements esp. snow, will give up date.
