This is a general comment relative to coach storage and slide seal inflation.
Jeff’s response is absolutely correct.
If a coach is being stored, and it has inflatable slide seals owners need to be aware that if the coach is not indoors or protected from weather slide seals must remain inflated. Any water entry into a coach has the potential to cause damage and in some cases that water damage can make the coach unuseable. That is a serious statement, but the greatest risk associated with water damage is mold and mildew. That creates a health risk and if widespread the cost to remediate mold and mildew damage can exceed the cost of the coach.
But if a coach stored outside does seal the slides against moisture penetration the use of an auxiliary compressor to maintain seal inflation can create a different type of moisture damage. Few conversions have air dryers or moisture traps of sufficient quality to prevent moisture from entering the coach accessory system. It is this reason why owners who intend to store coaches outdoors for longer periods need a plan to insure moisture generated by the auxiliary compressor is periodically removed BEFORE it enters the coach accessory air tank.
