Thanks for all the replies so far, it is very much appreciated. It would appear, without counting, that most of the respondents said that they leave theirs up and that makes me feel more comfortable.
The TV weighs about 7.5# and with the mount being less than 2.5 inches off the wall the shear loading on the wall parallel to the wall is maximized which is a good thing. I will leave it up and see what happens.
The 32" TV in the rear living area that came with the trailer is mouned on an articulated arm that, for travel, is stored "collapsed" with the TV "clipped" to the mount assembly. It is heavier and with a longer standoff from the wall but at the same time the backing support is likely more substantial too. I don't think twice about leaving this TV up (in other words, it aint coming down for travel!) and it probably also "jiggles" when going down the road, as the bedroom TV is likely to do.
I will update the thread after the next camping trip.
