Also, the old vent was screwed (although some of the screws missed or came out) into a wooden frame flush to the ceiling. Should I go this route or use nuts and bolts instead?
Thanks!!!

...I got the same problem like yours, Buddy. My old vent was installed back-ward by me and during a camping trip on HW, the wind blew it wide open, resulting a broken lifting lever. After buying the new vent, it is not the same but actually smaller. I did a proper work like someone said, with butyl tape and drill new holes on
fiberglass roof, NOT in the plastic vent and cover the old holes with body filler. After install the new vent, I give it a test with garden hose and after recent few rainy days without a single drop of leak. Tomorrow it will be sunny I will complete
painting the edge to match with the new painted trailer...Share with you my photos:...One more thing, when install the old vent I used aluminum rivets but alter the method with the new vent. Using aluminum screws with wood molding from inside(underneath) it secures WAY, WAY better...
