Who knows?
This subject may start a long thread but I think there are so many variables that the question cannot be answered. What sort of surface are you going to land on? Hard packed dirt? Water? Mud? Treetops? And are you flying a tailwheel or trike? The conventional wisdom in a production aircraft was to unlatch the door in some cases. But that assumes a door that might not open after the structure is damaged. Less likely in the case of an RV canopy.
And, from personal experience, you just might be too busy to think about the canopy latch.
