The Damages Sun Causes to an Uncovered RV 

There are several damages that the sun causes to an RV when it’s not covered. 

The heat from the sun pills off the paint from the exterior. This happens as you continue to expose the trailer to external factors like the sun.

It may not be immediate. But with time, you will see the result of not covering your RV.

Effect From The Sun Heat

The most common changes you see on the RV exterior are color changes from the original one. The changes in color are a result of the direct heat from the sun.

As the heat from the sun touches the body, it causes a reaction that expands the paint bond between the trailer body and the paint. 

As the reaction takes place continually, no matter the quality of paint your camper has, its color may likely change.

The pilling of the paint normally starts from the RV body. As the sun beats the RV it causes the paint to expand, which results in pilling.

Don’t be deceived by the manufacturers who will tell you that the paint is original. No matter how the quality of the paint may be, the sun has a negative effect on it, especially when it’s exposed.

The intensity of heat deteriorates the exterior as it mixes with snow. These are the major causes of rust.  

When there is a snowdrop on the exterior, it expands to smaller particles as a result of the sun. This expansion of snow causes the exterior to experience decay or rust. Mostly, the rust usually starts from the utmost top and the side of the tires.

The sun also affects the interior fabrics. It causes the interior fabrics to pull off from the wall. The foam that serves as an insulator begins to remove duel to the sun.
