If that's where you want to keep it, there are mounting options available that might
allow you to store a new flat screen out of the way. Otherwise, I finished my replacement
project a couple of months ago and gained a bit of storage space by using a swing arm mount
and moving my new 19'" to the rear of the entertainment unit in my Roadtrek. I now use
the space for charging stuff and as extra storage for whatever needs stored.
Here;s a link with some pics - they're not my pics, but my setup is so similar I didn't need to
add any more.
I went with a Sharp 19" very low power draw (29W nominal) so I could run it off
a smaller portable inverter. It also only weighs 8 lbs. so it isn't as likely to fall off the mounting
arm assembly (I hope!)
