I have been to sevral Upper, MI campgrounds such as you describe.. Try th T???????? Falls State Park just west of Paradise (Camping at lower falls).
But if you want to dump via those 3/4 inch hose things you need two or 3 things
`1: A macerator pump.. Min is a Fl0_jet portable.
2: some proprly colored hose.. Since I dump both wast tanks with this puppy mine is 50 foot,3/4 inch and BLACK it is also a winter grade hose (Does not stiffen)
My Gray trickle dump hose is 25 feet and does stiffen.
I have no problem using the dump station on the way out.
And you need a dual female hose adapter... Just in case.
