I have a TV permanently mounted in the motorhome butwanted to be able to watch  portable outside. I didn't want to sit it on a table or bench nor did I want to screw or bolt it to an outside wall. The solution I came up with can be mounted anywhere on a flat non-porous surface. Supports 90 kg and can be placed or removed in 15 seconds?

I attached a photo with the iPad but it obviously did not attach. I will need to crank up the computer.
