Here are 2 options. You can search out these brands at other places.
Ventline, This is what came from Sunline. This will fit your year camper.
Camco, they are an aftermarket mfg, and have good quality on many items. Not all but many,
You have to watch the hinge that it lines up correctly. The Camco 40161/40168 White Unbreakable Polycarbonate Vent Lid - Ventline (pre 200
& Elixir (since 1994) is what you are looking for. This one is made out of a little better plastic then the original.
I find that by using 303 Aerospace UV protectant on these plastic, vinyl and rubber items extends the life of them majorly. Best is to apply it when they are new and 3 to 4 times a year if the camper is outside all the time, or if stored inside, to 2 times. You add it after you washed the roof.
Careful when you get up on the roof. Unless your camper was a special order you cannot walk directly on the roof without precautions to spread your weight or you will go right through it. If you need help on how to do this, ask away.
Hope this helps
