Installing MaxxAir vent cover - question

I am getting ready to (hopefully) install a vent cover on my bathroom vent. I've installed one on another RV but the frame of the vent on the roof of that unit was metal. My vent frame on this RV (2007 Itasca Spirit 25F) is fiberglass/plastic. Before I go drilling holes in this puppy, is there anything I should know? Or am I way over thinking this (which wouldn't be a first)?

Any help would be greatly appreciated.

All very good suggestions, I may add another, just make sure that you have a very sharp drill bit to do the work, so you do not put undue pressure on the housing while drilling as not to crack it.

I found that out the hard way. Not on one of these but on another kind of thin plastic used in RVs.

I wouldn't think much different. Be careful drilling hole so not to crack the frame, drill on slow speed so plastic doesn't get to hot and be sure to use the large washer on inside of frame to spread pressure out on the plastic frame.

Try to drill the holes exactly the correct size for the screws. If possible to practice on scrap would be helpful. Too small a hole might crack the surrounding material when the screw is driven in.
