Got mine done in PG a few years ago, was allot less money than I thought it would be, hard part is matching colors, things change so much over the years. I was about $400.00 for a 10 footer and $600 for an 18 footer installed.
Its a much simpler awning for the slide outs as compared to a regular awning.
Just replaced the 19 foot awning on my trailer
365.00 shipped on amazon takes about 1.5 hours to change
lots of videos on YouTube of how to change them
