I have the 2011 Jayco Eagle 330rlts and for the bedroom tv the opening in the center of the door of tv cabinet is the size of the tv you can put in,, just measure inside door panel. I don't know what the weight limits are, as I don't want or need a tv in bedroom, we use that cabinet for blanket storage.
