Thanks to both of y'all for the ideas! Quahog, thanks for the pictures and the links. The articulating arm seems like a must, I'll be buying one like that. Cfd, if our bedroom was a little larger then the bolt idea would work perfect and I'd probably never have to worry about it coming loose, but our trailer is so small were only going to have the one tv by the couch. Thank u both for the info.
