Having built a large fiberglass sail boat I have no problem with mounting the side to side level on the front fiberglass cap with screws. Use stainless steel screws to ensure no rusting. Where the screw goes, drill a hole through the fiberglass that is just slightly smaller diameter than the screw diameter. Then, put sealant in the hole you drilled and also on the bottom side of the screw head. Don't over tighten the screw, but do make sure it is firmly holding the level against the fiberglass. When done use mineral spirits to clean up any excess sealant. Mounting it this way will ensure it will not come off and that you will have a leak proof connection.
Except on a boat, the fiberglass typically ranges from 1/4" to 2" thick depending on where.
On a trailer end cap, you might be looking at 1/8".
Very easy to accidentally strip out the hole and sealants aren't forever.
