bought these giant caribeeners at Lowe’s and they are perfect for attaching on the Trasharoo. They held everything from towels, to Kroger sack for trash to the actual Kitchen Sink (Sea to Summit. Love it). Let everything dry out and didn’t need a clothesline. about $3 each. 
I guess a lot of the smaller caribeeners would work but everyone has those right? I am a man and BIGGER IS BETTER.
Lol. Ride safe. And Clean.
