I currently have the Bestop Highrock rack on my 2013 JK and just got the Teraflex/MOPAR HD Tire carrier. Because of the way the TF bolts on, it does not look like my current rack system will work with it. The only thing I have seen for sure is the TF Alta and I don't feel like spending another $850. I have heard that Garvin makes one (or just started making one), that will work. Anyone have any thoughts on this? Have you used another set up with the TF?
