Having owned Jeeps for decades, and living where we have 4 actual seasons, I hate the zipper door idea from the second I saw that OEM top. That being said, if Roxor made one compatible with the extended ROPS, they'd have my $ tomorrow.
The OEM hard half cab option is a bad joke. HardCabs full enclosure solution leaves significant amounts to be desired, as it's more like having a topper on your truck bed, but it is the best option out right now IMO.
If something major happens to my Dodge this winter, HardCabs is getting my money baring a new entry into the market.
