Yes you have to remove the back in order to remove the securement of the old TV.

I done mine about three years ago. I wanted an RV shop to do it for me at first until they coded me a price of 3K dollars. So I decide to tackle it myself. I had to buy some tools, like a electric saw that would cut through the medal framing it had. I already had a table saw to cut the wood facing that was there already and it had to be cut perfect to the new flat screen TV. You also have to put a cross member inside the box in order to secure the flat screen support bracket. That was probably the hardest job measuring and cutting the plywood for the cross member. But the project come out perfect, and it looks just like a factory job.
