I installed this in a travel trailer and mounting it was easy once I found a stud to screw it into.  It is difficult to lock into place because the knobs are too small to grip easily.  Because the mount does not lock into the wall plate the television will bounce around while traveling so you must either strap it to the wall or remove it and secure it elsewhere in the RV.  The variable tilt feature is nice but the adjustment steps are too so large that the TV is either vertical or very tilted, with no way to slightly tilt it.  It's a acceptable mount, but probably not the best choice for someone who travels a lot.
