JMO, but alpha is going to say use their products, read a Ford manual and it will say use Motorcraft.
If you look at the link I provided it says it is compatible with all TPO membranes. Anyway it's your trailer and your choice.
I've installed too many vents to keep count, and have never seen a need for eternabond tape. Haven't ever had one come back for any leaks. But again it's your trailer and your choice. You have to seal the edges of the eternabond , so IMO your adding a step and work that isn't needed.
