I have an '05 Bounder with the same window treatment. I removed them and put in wood Phoenician blinds and curtains.
There were four L brackets on top and two on each side. I used a cordless drill with a 6" Phillips bit to remove the four on top. That gave me enough room/leverage to get behind the cabinet. I did all four windows on the drivers side.
