I have a solution for you, but we don't have access to information that tells us exactly what pipes are found on particular coaches. The # TR38A has a spigot for the black water pipe and a hub for the grey water pipe, so if your coach has those fittings then this would be the correct valve for your 2018 Minnie Winnie 2108ds.

You will need to remove the current valves to determine which fittings are on your grey and black water pipes, but for reference- hubs on the valves slide OVER your RV's water lines while the spigots on the valves slide INTO the water lines. When you take off your current valve, pay attention to if it slides into your pipes or over them.

Once you determine which one you've got, you can use any of these to give you a valve fitting that combines the grey and black water and makes it much easier to empty your tanks with a single 3" hose.

- Valve # TR38 has a 3" hub and 1-1/2" hub, both of which slide over your water lines. The 3" hub slides over your RV's black-water line while the 1-1/2" hub slides over your gray-water line.

- Valve # TR38A (the one you were looking at) has a 3" spigot and 1-1/2" hub, and the 3" spigot slides into your RV's black-water line while the 1-1/2" hub slides over your gray-water line.

- Valve # TR38B has a 3" spigot and 1-1/2" spigot, both of which slide into your water lines. The 3" hub slides into your RV's black-water line while the 1-1/2" hub slides into your gray-water line.

If your current system uses something completely different then let me know what you find and I can see if we have anything available that might work.
