I just bought a wrangler, and it only has a soft top. I've been looking into getting a hard top for it, and from what I've found, the only thing that would make switching from using the hard top to using the soft top, or the other way around, is that the soft tops use a "belt rail" that is bolted to the top edge of the body tub, to hold down the bottom of the soft top. this rail, as well as the frame for the soft top would have to be taken off in order to put the hard top back on. if you use only the soft top in the summer, and hard top in the winter, I guess it wouldn't be to bad, 'cause you'd only have to install and remove the soft top "belt rail" and frame twice a year. oh, and I'm not sure about other ones, but the "bestop supertop" will work with your full steel doors.
