I have a 1998 carri-lite. Being an older RV, it had space for a big body TV. Above that space is a mirror and a cabinet that opens in the bathroom. There is a lot of wasted space and the TV is only stable high. I am planning at some point to take off the mirror and mount the flat screen TV at the top and maybe put an electric fireplace in the middle and use the bottom for storage because the breaker box takes up some storage at the bottom.
So, maybe you can move your TV up and the storage down a bit. Not sure of your layout.
