Just got back from Florida April 5, 2019. My Ram Sport has been in my garage since January 23, suspension set at normal ride height, battery was disconnected. Air suspension was still at normal ride height. Reconnected the battery, started right up, I did not hear the compressor start, so that tells me there are "NO" leaks anywhere. I had the suspension purged in December after getting messages. From now on I am getting the system purged before freeze up and change the air filter behind the right tail light. I really like my air suspension system, but Dodge needs to make the system completely closed loop like an air conditioning system and stop checking those air lines behind the right tail light for blockage.
