Yes there have been quite a few different discussions on this, I'd suggest doing a search for TV although that will also pull up a bunch of "Tow Vehicle" discussions.
Our TV in our 30SK sits in a hole and mounted on a bracket with four screws. They are screwed to one of the metal wall studs I believe. For traveling I mounted a couple of eye bolts on the wall in back of the TV and have an adjustable strap with hooks that holds it in place. To further protect it I put a piece of slit pipe insulation along the sides. I also put a wooden post into the detente between the bottom of the TV and the counter.
It seems to work well.
We strap the TV tight against the entertainment center with a strap that is mounted high and low on the back wall of the entertainment center in the center of the TV.
In the bedroom, we just upgraded our mounting system as one of our poorly maintained California roads (CA is pretty much bankrupt) bounced the TV out of its mount which were a couple of spring clamps. The new solution is a custom cover (made of a towel) that slips over the TV and is secured at the bottom with 2 velcro strips. We then have 2 "belt loops" through the cover which has a quick-disconnect strap going through. The strap is secured to the back wall of the cabinet.
