The first thing to know is that every campground is different. Many of the campers that have two sewer hose connections dual hookup are travel trailers or 5th wheels that are longer than 30 feet.
I opted to go with three hoses that can be connected. That means I can have 10, 20, or even 30 feet if needed. It comes with two 10 foot hoses and a sewer adapter to connect the hoses to the campground sewer sewer.
The adapter has a handle which makes inserting the adapter into the sewer drain easier. You connect each of the hoses to the wye and then connect the wye to the sewer adapter. I chose a Valterra Rotating Wye Adapter. While most wye adapters were fixed, the Valterra enables the hoses to rotate which can make getting things set up a bit easier.
You need to support the hoses. With the weight of black and gray water filling the hoses and the complexity of a multi-hose setup, there is too much chance for an unwanted RV movie moment. Keep in mind that there is nothing stopping fluid from flowing from one hose into another. With two heavy hoses pulling down on the wye fitting, even a fairly good connection could come loose.
To support all of the hoses, I deploy three of these supports. These supports are unfolded and hold the RV sewer hoses at an angle to help fluids flow toward the sewer connection. The first time I used these supports, one of them broke leaving me with two equal lengths of support. In a way, that is a good thing. It means I can use the support more flexibly to get the right height over a long length of hose. What you really want is for an even decline.
Consider getting both 10 and 20 foot versions of the support if you can.

As these items have the potential to get messy, I line the bucket with a clear trash can liner.
