My  71  25 ft tradewind  has a small pin that comes out of the door near
the latch,it slides left/right to lock
the main door latch,  also it is not uncommon  to put a small pin latch
like on cheap  barns to lock just the 
screen door ,   at least some noise will be made so you can shoot them or
greet them,
