I use the Mopar window storage bag for TJs. It accommodates the upper door skins, but because of this it won't fold or roll up with the windows and skins inside. Because of that, I've never tried to carry it in the Jeep while on the go. I'm sure it could be done, but doesn't seem very practical to me. It also appears to be out of production, but there is probably some NOS still floating around out there.
