Isota cargo box

Im looking to pull the trigger on Isota’s cargo box and leaning on their half box. Just thought it would be nice to keep a separate cooler bag behind or in front of the box. Does anyone else have this box or the full box and can share how you like it? Expensive box, that’s whey I want to weigh out my options out there. Also has anyone able to secure this box so that you need a tool to remove the brackets, easy enough for the owner to do, but just long enough that someone doesn’t walk up to it and snag it.

Any other boxes besides factory to look at? Utv doesn’t make them anymore.
