A cold surface or cold air produces condensation when warm, moist air contacts it.  A more detailed explanation of dewpoint and relative humidity can be found by googling those terms, but for this discussion, the short version will suffice. Condensation occurs in RVs for the following reasons:

A cold RV’s interior walls and windows are struck by warm, moist air from outside.  In early spring when the RV is still cold inside after having been in storage all winter, this may happen when it’s hot and humid outside.

RV walls and windows are heated and moist by warm, moist air produced inside.  People usually experience this when using RVs with inadequate insulation and single-paned windows for winter camping or full-time living in cold climates. Whatever the cause, dampness causes your things to become damp, mold and mildew to form, and dust mites to spread farther and wider.

What is the best way to prevent condensation?

Getting rid of condensation’s causes is the most effective way to prevent it.  In order to achieve this goal, all tricks and techniques boil down to two key points:

  • Ensure that indoor humidity is reduced.
  • Air pockets and cold surfaces should be removed.
