Does drilling a hole compromise the integrity of fiberglass?

Though still in the planning stages of purchasing my fiberglass RV, one modification I know I will want is to put a SATV outlet on the outside of the trailer. I would like to have a living room area set up outside under the awning for those nice evenings and watch TV after dark. I am a TV addict, and will be travelling alone, and TV makes for good company for me. My plan is to be able to remove the TV from it's brackets, move it outside on a small table, and plug the cable into the outlet leading outside. I want to make this a simple one minute process. Sounds simple to me.

Does drilling a hole on the exterior wall compromise the strength of the fiberglass? I realize I will have to caulk it well to prevent water leaking inside. But I don't want to risk any cracking in the fiberglass.

Has anyone else installed a SATV outlet on the outside of their trailer?

A well caulked hole should not pose a problem. One thing I noticed on my Scamp was anything under the belt line trim does not get that much water. It tends to drip off the edge of the belly band and not run down the lower portion of the body. I installed a 120V WP outlet on mine and have a 12V I am going to do next to it for a my Fantastic Fan. Be carefull, measure twice, cut once.

The simple answer to your question is NO it will not compromise anything. A small hole that is properly sealed will not cause any problems.

We have an outside antenna on the rear of our trailer. I ran the cable in the access door where the shore power and water hookup are. If not there I would use a rubber grommet in the hole. I have a coffee can full of grommets for such projects.

If the manufacturer cutting a hole in the shell for a window or a vent fan does not compromise integrity, a small hole surely won't. Drill away. Just double and triple check where you are drilling. If you drill in the wrong place, it can be repaired, but why go through that hassle.
