I have not but have been tempted to consider this. Check out this thread: https://www.jlwranglerforums.com/forum/threads/jeep-jl-rubicon-jlur-3rd-row-seats-install.33773/I have one for my 2008 JKUX. I used it a lot when my kids were little. I bought my jeep brand new and got that removable 3rd seat pretty much right after I bought it. Has anyone done that with her JLU?
