The water tank thread got me wondering what system folks like for water draining from the sink.

I'm curious about the specific adaptor pieces connected to your sink trap, and then the hose/pipe material used.

I'm trying to design a system that will have minimal bulk, will be easy to keep out of the center of my under-sink cupboard, and most importantly, will end in a flexible tube or hose that I can run directly through a hole in the floor (if I'm remote camping) or run into a large bucket/jug for "gray water" when in urban areas.

I used these parts for my small (bowl size) sink.

This combination allowed me to attach a 3/4" hose that went toward the back of the cabinet where it curved toward the floor. The right angle vs. straight drain outlet saved a lot of space in the cabinet below.
In my setup it goes to a 3 1/2" Waterbrick that is my grey water tank. Plenty for our trips!

I just used one of these and it works great. Under $12 at either Amazon or Walmart.com.
