Removing overhead entertainment center

I pulled out a he big Samsung TV today; vert heavy! The supports on the side are identical to those shown in the parts manual for my Winnie. If I remove everything I would need to do a lot of finishing insiden not sure if I want to at this point. I will put light weight flat screen up there for now and use it that way for a while and see how things get used. Good to have monster TV out!
