This is what I've done to mine.
When we first got it, on the way home I threw my shirt over the door,
slammed the door. Didn't care for that. Tried to figure out a curtain
solution. But since it was taking us a while to get home, my daughter
liked a butterfly car window shield we saw. So I purchased one and
velcroed the corners. On my trailer there's not any room between the
screen door and door. I'm not comfortable taking windows
out which would be the probable way to get the window where you could
do a tint job. Whether temporary or permanent, this is working for us.
