Made a new storage area using Coroplast

Has anyone else used Coroplast to add storage in your RV? We just added made a shoe storage bin under the floor with the hopes that it actually holds up. I think it'll do the trick assuming the kids don't try to climb in there. My initial design had flaps that were glued and riveted for support, but needed to cut them off after I realized a measurement error.

Here's the video of how I did it
