My DH did a lot of research on TV lifts before we put one in our '99 Damon Daybreak.
We found one that would allow us to put in a 60" TV in a very short and narrow area.
The
Nexus 21 lift is an awesome lift and their Tech Support is great.
You can find a
video of the list in action here on my blog. You can also find other info about the installation throughout the blog - which is listed below in my signature.
Good luck in whatever decision you make- I am sure you will love it.
