Could you mount the articulated arm inside a hatch? Then just put the PAWS mount on that.
PAWS mounts are, IMO, incredibly costly for a small piece of plastic. My TT has the exterior mount, the television part was supplied, but the interior mount was missing. I mounted the television permanently on an articulated arm inside. I have no reason for watching TV outdoors while camping. I used the PAWS mount on a family camping sign I put out during setup.
Just thinking. For the cost (& weight) of a small television, you could put one on an articulated arm permanently in an exterior storage compartment.
