Our recently acquired Cheyenne has a Z1 awning with the Privacy Room sides and front. On our first attempt to errect it, we discovered one of the zippers (side to roof) was broken. After a few attempts to undo the zip (which was undamaged) we had to break the zipper to remove it. As the zipper is part of the side panel, The cost of having the zip replaced was exhorbitant! After looking on the web, I found an American company 'FIXNZIP' who can supply zippers which are easily fitted without the need to undo stitching, etc. If you've a problem with a zip it's worth looking at their site. For $9.99 it solved my problem - and the expense! :thumb::thumb: works on tents, clothing, etc.
