let me answer that NO!!!!!!!!!!, I can't tell, do you have a bed light? If not, I would take the interior light down, and get a can of the spray foam, and spray it up in there. If you have a bed light, remove it, and you'll get more of the hose in between the two pieces of metal. Or you could do like Bucket said, and put a head liner in, and yes it make a big difference.
