Had a small LCD TV between the driver & passenger seats up on the front cabinet. The TV mount was purchased from a company called Dynamic Mounting LLC.

The mount can handle up to a 100lb YV so my 25lb smart TV was no problem. The mount is fully adjustable and will stay in the stowed position. The swivel from left to right is also adjustable. If I do end up with ANY movement while driving I'll secure with a couple velcro straps.
First picture shows you the original setup before purchasing the mount. I would place the 40 inch smart TV on the dash. Had to stow it on the bed every time we moved. Was getting to be a real pain in the rear end. Also, very easy to damage the screen while moving around.
Note how I had placed the 40" TV on the dash. Moving back to the room was a real PITA.
This shot shows the screen in the down (viewing) position.
The mount is VERY stable when stowed. I don't think I will have any movement of the mount while driving down the road. If so I will make up a couple velcro straps.
The white covers are used to hide the cables routed thru the mount. They cab be painted black or what ever color you desire.
Yes, $400 for a mount is on the pricey side BUT this is a well engineered mount. I feel very safe driving down the road with this mount holding the 40" smart TV.
