Thanks everyone for the input. I have checked with Gulfstream, and was told that my roof is 3/8" plywood covered with rubber membrane. Yes, these are 2-100 watt panels. I have decided to go ahead and use well nuts 3/8" x 1". these are supposed to work for material from 5/16" to 5/8". My kit includes their Z-brackets, so that is what I will use.
I have read to put Dicor sealant around the hole before inserting well nut, as well as Dicor over the bolt head when done.
Panels are arriving later this week. Hoping for the best.
Get some 3/8" OSB plywood and practice with the well nuts and make sure your happy before application on the trailer.
Be careful not to get the membrane caught in the drill bit when drilling 3/8 is a pretty big hole.
to avoid damaging the membrane with the drill bit I used an appropriate size hole punch to take out a nice round piece of membrane when I screwed my brackets down. Dicor under the bracket before the screws installed, then Dicor on the screw heads and bracket frame
