I agree with the above posters who recommend using hard pipe instead of the slinky supported by whatever. The slinky takes a beating from the sun and becomes hard and brittle after a period of time. Also, the birds peck holes in it, the weed wacker guy cuts holes in it, and for some reason it always starts to leak after a while.
Our trailer spends the whole summer in our sons campground and I have it hooked up using rigid PVC pipe. Got everything at Lowes that is needed except for the fittings I already had for the slinky system.(picture #2)
The following pictures will show how it is hooked up. There is a rubber fitting that goes over the campground sewer pipe and reduces to the trailer pipe.(picture #3)
