Like dstankov I also shut off the coach valve first and then waits till flame dies. I took a heavy duty zip tie and put it around the coach propane tank support bracket. I use a heavy duty Velcro wrap to secure the hose in the tank compartment on the zip tie. I know you can smell propane on the hose but doubt there would be sufficient gas to cause a problem. The only reason I store my hose in the tank compartment is for convenience and easy access.
