I had one on my Centurion Elite-V for about 10 years. It was solid. I could fold it down in less than 10 minutes. I had no speakers but 4 racks on the tower. I was also able to tie our tube to the top of the tower. It was also easy to install. I did use Monster board and ski racks.
I could also have a bimini that fit under the tower which was nice. The model I had was basic though.
