It is generally recommended to retract or bring in your RV slides during a storm or inclement weather conditions. Extended RV slide-outs can create additional wind resistance, making your RV more susceptible to damage or tipping over in high winds. Retracting the slides reduces the surface area exposed to the wind, helping to improve stability.
Additionally, storms often bring heavy rain, and extended slides can create more potential entry points for water. Retracting them helps minimize the risk of water intrusion, protecting the interior of your RV from potential damage.
Flying debris is also an issue. During a storm, there is a higher chance of debris being blown around. Retracting the slides reduces the risk of things hitting and damaging the slide mechanisms or the slide-out rooms themselves.
