Michael & Debra, perhaps it is a geographical question as you are in Mexico and most members here are either in Canada or US and we are a small group. I'm aware of members in fiberglass rv forums here http://www.fiberglassrv.com/index.html which a much larger and diverse group that have taken measures to protect their rv. You may want to pose your questions there as well. You may find the answer you are looking for.
