YEAH. I needed the bigger one on the trip down to hold necessities 'just in case' and I had a smaller, insulated one packed for beach stuff. I wanted to take the smaller one home so I packed the bigger, empty one. As it turns out, the bigger, empty one when it was in use was fine. I had such a big main suitcase with me, the 2nd one didn't knock it off its wheels. all worked great..
