No standard kit or mount. All depends on TV size and location of the install. Some flat wall mounts, some with articulating arms. Many folks (myself included) have used standard household type mounts. Then used varying hold down systems.
On one of my trailers, I run a lashing strap behind the mount. The screws into the wall secured both the mount and the strap. When going on the road, I push the TV tight against the wall and cinch up the strap.
