    Must have for RV's or Campers
  

*by D***. on Reviewed in the United States 🇺🇸 on April 27, 2017*

I have two of these in my motorhome (second one is a smaller size for the bedroom).  Also installed one in a previous rig.  They're excellent.  The lock keeps them from flying around while you drive.  (Don't try and use a mount designed for a house).My only wish is that it would be nice if it could keep the TV from rattling on rough roads.This one is above the driver's seat and I really like that when I'm stopped I can pull the TV out and get the set a little closer to where I'm sitting as well as tilt it toward me.More than anything, by replacing the old box TV's with flatscreens that are mounted I've picked up quite a bit more storage.  I have them mounted where the old TV's used to sit and because they're swing out and to the side, it allows the TV to hide the stuff that's stored where the old box TV used to be while making it easy to get behind the TV and access the space.

Unlike the complaints, I have had no issues with the unit locking with the TV mounted.  I can only assume user error on their parts. The chain is a bit flimsy though, so don't pull too hard.  Mounted a 32" TV without issue, tilt holds fine.  Using a smart TV so no cables other than power.
