I also have a campster, and one of my window latches broke. I went to local locksmith and he went to a spare parts box had a plastic one that looks a bit different but works well. The sliding part fit in the door window frame slots. So don't give up, they're out there.
I just googled "rv storm door vertical slide latch" there are lots of them singles and set.
