How to Know if Replacement Vent # BV0554-01 Is Correct for Roof Vent of Trailer

Question:

Item BV0554-01 appears to be the right replacement dome for two of my roof vents. The inside diameter of the unit is 13 1/2 x 13 1/2. Inside trim is 16 x 16. Can you help me with this to verify Im on the right path. I can see no identifying numbers on the units. Thanks,

What does the hinge look like? If it's a continous metal hinge like what you see in the picture I attached on the left side then the # BV0554-01 is the correct replacement vent.

The second picture has a few other hinge designs for you to check out in case what you have looks different.
