Lock and Ride Storage

I really wanted to get the Lock and Ride Cooler Box but already have fitted the spare tire holder part number 2879464. The Polaris RZR accessories web description clearly states that the 2 will not work together. However the lock and ride STORAGE box does not carry the same caution. To me from the photos they look identical. Does anyone have any insight of experience of these products. I am wondering if Polaris is being over cautious here. To me it looks like if the spare wheel tire was mounted as high as possible and swung open when using the cooler box, it would work.

I have the XP4 1000 2015 fyi

Appreciate any help/thoughts.
