TV mounting

I have used the type anchor that DougE has linked. My concern is that the combination of the tv and the bracket will be too much weight while on the road. I think there might be too much weight and will pull loose during travel. Stationary application would be fine but who doesn't move the typical rv? If you have a storage shelf above the bunk end might be a better choice than the wall as it can be beefed up to allow for the josseling that road travel creates.
