VESA mount location on 32 inch Select Series inside trailer measurement

I am looking to put a 32 inch Roku Select series in my camping trailer. I have an existing VESA mount inside the trailer and I need to find out what the height is from the top of the VESA mount location on the Roku TV to the top of the TV. The trailer wall mount is designed so you can lift the TV up out of the wall mount and move it to another wall mount (like the one on the outside of the camper). So I need to make sure I have enough height to work with if that makes sense. If you are an owner of one of these TVs and could send me the measurement I would be truly grateful!
