My Chaparral has those mounts for all the TVs. I pull the one out of my front BR and use it outside. It's nice to have something standard that works well, but if you want a swivel mount, you'll be replacing them with something aftermarket. Others have asked Coachmen for extra mounts, but I have not found them retail.
