Eberspacher re-circulating air vent location measurements

Insulation behind the panel as its not in use, not mine BTW, just a pic i had.
Loads of info here if you havent seen it incl cutting diagrams, i only had a quick scan

Would this vent be better placed higher up, where it can't be blocked by bedding etc ....

 

Doesn't really effect me with my Viking conversion. Beds are in the front or up stairs. You have to put it there anyway due to the way it's made

 

Turns out the vent hole is here. Dohhh
