We borrowed a friend's camper that had an ingenious screen door mechanism. When it was closed and latched, you only had to slide down a handle formed within the plexiglas and it would press down on the latch to release it allowing you to open the door without having to open an access hole to hit the latch.
Our current camper doesn't gave this feature. Instead you have to slide a window back each time to reach in and release the latch when you want to exit the camper. Is there a way to replace the sliding portion of our door with a system similar to my friend's door?
