Thanks Burl! Your carpenter friend did a nice job there. I did a quick and dirty boxing in and reinforcing of the opening end (half, let's say) of the TV enclosure, so I could do a likewise quick and dirty simple fixed mounting of our 19" Vizio LCD TV. I included a shelf which created a bottom opening that can hold our DVD player and even our DISH network receiver if we decide to bring it.
Just today I finally stuffed the back cavities with insulation (thanks to a post of yours). Since I had not finished the back of the opening and didn't want all that insulation dust exposed, I covered the back of the opening with Reflectix. Prior to doing this, the mounted TV looked perfect because the rear part of the enclosure just disappeared in the dark behind the TV, lol. Now I can see the foil, so a black fabric covering may be in order at some point.
Here is a photo which shows a 12v outlet added so I can run the TV off an 80w plug in inverter. It works just fine, and is enough power for the TV and the DVD player (22 and 6 watts respectively), or the TV and DISH receiver (22+30).

I also added a 12v outlet and 120v outlet under the dinette seat, which makes it into a nice laptop station.

Finally, I added another outlet by the kitchen. It can serve the counter top area but my main motivation was to have a separate circuit for an electric space heater. I had an open spot on the circuit breakers (labeled water heater). I ended up putting both of the new outlets onto that breaker.
