There are several grades of Etarnobond. Which is stronger or which will pull the metal corners best?
Eternabond Roof Tape has a vinyl wear layer. Eternabond Webseal has a fabric matrix but must also be painted to survive in UV light.
I don't mean to rain on your BBQ, here, but I think you're going to be disappointed and a few dollars shorter by just using tape for this repair. I've tried the tape repair in pretty much the same situation and it doesn't work that well. Since the surfaces you're trying to join are now loose and will move when towing, it will not hold with any kind of tape I know of. If you can spread an epoxy in the joint and clamp it closed until the epoxy sets, the tape will do the rest of the sealing. If it was me, I'd use a light metal angle piece of aluminum and fasten it to both surfaces, sealant applied under and over, and sleep sound.
Another way of bringing the two surfaces together is to back the trailer close to a garage or shop wall and use boards against the wall, to the trailer to force the joint closed.
