An RV air conditioner leaking water inside when it rains is a common occurrence, and it’s one that you must address as soon as you notice it to prevent widespread and costly damage.
Your air conditioner is attached to your RV’s roof with mounting bolts, and water is kept out courtesy of rubber gaskets that seal against the RV roof once the bolts are tightened.
You may assume that your RV air conditioner leaks when it rains due to the location of the drip or water damage, but it’s possible that water is coming in from somewhere else entirely.
