J Rod, I don't secure mine for travel and it hasn't fallen on my head, yet! I through bolted the bracket to the plywood before installing it. I then mounted and locked the TV to the bracket so it could not move vertically. I then installed the plywood with TV attached to the cabinet. There are 3 very strong screws top and bottom holding the plywood. Before doing this I did reinforce the wooden mounting pieces that the screws go into. 18 months now and no problems.
I also keep my front tire pressures at spec for my axle load (95psi) which helps reduce the jarring you get hitting potholes etc.
