How Thick Is The Roof

[fwernlein]

I would second Davids recommendation for rivet nuts. A solid blind
hole fastener system. There are types with rubber collars that will
provide both the strength and the weatherproof seal you need.

I have used on the bus and my boat with good success. They save a
significant amount of cussing where you can not easily reach the back
side of an installation.
