double tank drains

Try this: Camco RhinoFLEX RV Wye Fitting

I use a y connector at the sewer pipe with regular sewer hoses

My FW has two drains about 10' apart as well (both drain black with 2 baths so garden hose is not an option) and I use the Dominator sewer hose kit as it has various lengths of hose available and also a Y. Quality seems to be much higher than the cheap stuff from Walmart, etc. Not sure if there is any one method that is better than the other as I can see both ways working fine. I wanted a higher quality hose and it happened to have a Y so I went for it.

setting up a tee is just extra work.

I just move the hose to the galley drain when needed every 3 to 10 days.

I run the kitchen drain thru a garden hose to the campground sewer. There is a fitting with both 3" and garden connections.

I wouldn't hook the outlets together on the trailer because of getting flow back and forth between them.

I don’t keep grey tank values open. How will you flush out the hose after draining the black tank? Heck, how will you flush out the grey tank?
