I recently bought a new 2020 Rubicon with the fancy one touch roof. Have to say that I LOVE it so far! That said, have a weird question. The back window isn't meant to come off (easily), so when the doors and windows are off, and the top back, is that back window intended to just stay down and in place? Are there any concerns of stability with everything else off and that window catching any wind drag? Thanks in advance!
