Sorry to go slightly off topic, but if the skylight itself has a small crack, what product would work on that?

I would use a good caulk or sealnat.
I used Quad Max on my camper:

When I did maintenance one time before my skylight overhaul repair, I tried Eterna-Bond on the flat flanges where it meets the roof. I did not have good luck with that method. I thoroughly cleaned the surface as that is very important, but it did not stick which prompted me to completely remove the EB (not fun on the portion of the roof where it DID adhere.

I have read where others have used EB on the skylight with better results than me. I guess you could try it on a sample area otherwise another method might need to be used.

Presuming you're not talking about the $20 crank up vent. If so you can get a new cover piece super cheap.
If you want transparent and last a long time, I would use a piece of clear paint protective film like 3M Clear Bra or similar.
And I wouldn't be afraid to put it on the inside instead and save the trip onto the roof if you were so inclined.

Climb up the ladder and fall thru the skylight?
Seems odd.

Yes, needed to sidestep once up on the roof... it was the only place on the back of the TC that they could place it due to the floor plan layout, not too bad once one gets used to it.

I did use Etrna bond for the actual roof repair. I needed to peel it back about 10 inches to expose and work the roof framing and then laid it back down with the EB on top and all around.

I did not want to EB over the new skylight flange since the first attempt (on the old bubble did not stick.) Also- did not want anything over the new, except for Dicor, so that if the skylight ever needed future replacement then it would be easier to only remove sealant for any new bubble install.

BTW- there is a strip of butyl between the new EB on top of the roof and under the skylight flange with the sealant over it all including new SS fasteners.
