No, don't take the frame off. Unzip the two rear window zippers just up to the top corners so you can reach in from the tailgate and relax the side tension bars. Then untuck the bottom edges of the two rear lower corners from the bottom rails for easy access to the side zippers so you can unzip them (you also have to untuck part of the edges on the upper door frame to get them all the way off) then tuck back in. On the back, you bring one of the two zippers over to the other one to get them off on the end of the zipper. Tuck the rear corners back into the bottom rails and snap the tension bars back into place. Hope that makes sense... I'm going off of memory from about 2 years ago.
