I used a 6" vinyl fence post cover and then made a "tray" for inside it out of a 5" vinyl gutter. The gutter sides into the post cover and eliminates the need to stick your arm "up to the shoulder" inside the dirty fence post cover to get to the "second hose inside"... Just lay the hoses in the gutter, slide it into the post cover, put the cover on and tow. When you need to use a sewer hose, remove the end cover, pull out the tray and take the hose off the tray. Simple and effective....

An "added plus" is you can use the gutter as a "sewer hose support" when camping. Just lay your hose in the gutter and it will "slope down to the sewer outlet at the campground"...
