Question:
I have read other posts here on measuring the roof vent size. To measure on top do you measure ID or OD oF the vent? Is it the same measurement whether replacing the cover or the whole vent?

The hole size that our roof vents are designed to fit is 14 inch by 14 inch. If you measure the opening and get that figure what we have would fit. If you measure just the lid it'd be most likely right around 13-1/4 inch. This size is very popular on trailer roofs. So much so that we rarely ever see anything different.
The part # V2092SP-28 is our most popular style of roof vent to fit that opening size.
