I am wanting to add roof A/C to my Fleetwood Graphite. (10' box, 2 piece AL Roof). I have looked around quite a bit and can't find an answer . . . I have a roof brace installed already- mid-roof in front of where A/C would mount. It has holes for power cord. Do I need a second roof brace in my roof? The parts site lists two different braces available and the brace kit comes with two braces which leads me to believe that two braces are needed. I have dealer installed Yakima rails up front, so maybe original brace was added when rails were added to the roof? not sure. if I only need one brace, I'm all set. but not sure that's enough. Can anybody say for sure that owns a Fleetwood / Coleman?
