.So - how do I attach the rail to the side of the TT (fiberglass?) Screws? Pop rivets? I'll probably use ProFlex to seal it.
If it were me I would not worry about finding studs provided there is a nice prop-type support under the RVQ once it is attached to the trailer. With a brace or two underneath, and extending some way down the side of the trailer, the tendency to pullout is reduced and the load on the rail is more a shear load.
As for attaching the rail to the side - I would make sure that the right screws are used. You can even use hollow wall anchors and you'd be laughing. I would probable make sure I install maybe 4 to 6 such screws. Also I'd put a bead of exterior type silicone adhesive on the rail and then screw it in place. Then you're all done!
Now, I have an RVQ that came with the RV but it lives in my garage as I don't want to barbeque so close to the RV. Don't want any smells and grease sticking to the trailer or awning. Instead I use a tabletop grill which I set up on the campground picnic table many feet away. :)
