When I was camping in a tent (now in a trailer) I found my Trasheroo to be good for carrying sleeping bags, air mattresses and camp pillows (2 of each). They're light and if it was raining I'd throw everything into a garbage bag and then put it into the Trasheroo. When at camp the bag would be empty for other uses … like trash, wood, etc.
An unanticipated use was for lacrosse. I coached for years and my kids played. After a day in a variety of weather, but mostly hot and wet, the equipment of two 13 to 21 year olds developed quite an aroma. The trip home was always better with their stuff in the Trasheroo.
Also, I think I saw this here on OB but I could be wrong. I recently put a 10 gal. Rubbermaid pail in my Trasheroo. It's a lot easier to use now and it looks better when it's empty or even half full. I keep an axe and mini shovel in there and add other things as needed.
