I put mine in a customized storage compartment mounted on the rear bumper.

Ok, so it's really just an ammo can but the bottom is lined with rubber to reduce wear and tear on the walls of the discharge hose. I rinse out the hose, stuff it in the box and snap the lid on. I just open up the lid when I get home and let it all dry out. How I place it in there keeps all of the liquids within the hose and nothing dribbling out. It's been working great for years. It handles the 20' section just fine but wouldn't work for anything longer.
