I personally wouldn't do it because of potential leak issues, but there is thread here somewhere with pics and maybe video on installing an entertainment center in the overhead. If I can find it, I'll post a reference.
Given the problems that we have experienced with leakage in the cabover area, I am glad that it is open and easily accessible. While we will continue to use it for light storage, I don't see building anything that would limit access.

Our 1998 Safari has the entertainment package layout with tv, storage, and a single bed that slides under the cabinets. It is a very nice design. The rv is in storage and I don't have a photo of it but, we'll be using it soon and I'll get a photo of it and post it so you can see the design.
We're not here for a long time, let's have a good time.
