The Essex was the only Newmar model that I know of which had a tv on a lift in a cabinet, along with the optional fireplace.
We wanted the same thing, so we rough sketched a cabinet design and had Newmar build it in place of the large couch when they built our RV. Being first timers we had Newmar build it, but next time we'll probably wait and have one of the local Nappanee cabinet makers build it for us so we can be more involved in the process. Running the wiring needed, if it's in a slide, could be challenging. We originally wanted the TV on the passenger side, but the raised slide would have limited the size of the TV smaller than we wanted. We ended up with the cabinet on the driver's side, which allowed for a larger cabinet and holds a 52" HDTV on a lift and also provides lots of storage space in front of the TV. Most people don't want a TV quite so big,
so the side with the raised slide is probably adequate. Even though we're currently having issues with our lift, I still recommend the Nexus21 lift, which has 24/7 support and a five year warranty. Their website is:
