There are many many older threads regarding this same issue if you search around, you'll get lots of help.
What I decided on was mounting the lcd tv on the wall above the dining table window, but with the rear slide, I have to stowe it during travel. Others buy the swing arm tv mounts and affix them to the tv cabinet. I use the provided tv cabinet for added storage and for the PS2 I use as a dvd player. I bouhgt a round plastic mouse hole and drilled through the cabinet to run the wires out to the tv. I even did a 1 up and got an rv mouse hole with a power cord door and drilled to the outside to run the wires. I mounted an aluminum tv mount on the outside of the trailer to hang the lcd for the big games. (side note: mouse hole and tv mount cost less than $35 total online)
