Razorback cargo rack

I’m seriously looking at purchasing the Razorback Cargo rack/spare tire carrier for my ’15 Trail 900. The carrier setup is a pretty big chunk of change, but really looks nice. I was wondering from those of you who have one, what your experience has been, good and bad. What, if anything, do I need to watch out for. What, if anything, would you change or do different. Thanks for your help!
