Has anyone seen a cooler rack that could be added to the back of the P4 attached higher (and removable) on the roll cage so that the tail gate door is still able to open? The storage space in the P4 is so minimal I am trying to find ways and things to add that would work. I have a buddy with a Ranger and he added a sweet cooler rack, but have yet to see anything for our P4s. Any ideas?
