The only gotcha is that countersunk screws will lead to gelcoat cracks. I'd use cap screws and live with the exposed heads.
I've never heard of that probability. Any links? A properly drilled hole and a smooth countersink shouldn't damage the gelcoat enough to cause cracks should it? I don't have the knowledge to guess.
I'm not even sure I have gelcoat. Because my RV doesn't shine like water...which is what I suppose gelcoat causes. It just seems like smooth fiberglass when I get it washed, and then a wax coat makes it shiny. It's now 16 years old and there's no flaking of the RV surface anywhere (but there is on my car) so I don't think I have gelcoat.
You have gel coat on at least your front and rear caps. Once it starts to oxidize it will get dull.
