I just did the same thing on my 19CCD. The street side awning rail is already there, so it's not a big job to install it. You have to add one to the rear for that window awning.....but that's not a big job either. I would offer to get the awnings for you as I'm an authorized Zip-Dee dealer, but it would not be very nice to show up at your dealer with the awning in hand, just to have them do the install.
I do offer a 'Forum Courtesy Discount' though if you want to do the job yourself.
