At 15000 miles on the desiccant pack I wouldn't bother .
Depending on the weather conditions the coach is driven in the service interval can very dramatically for example if you were in a very cool and high humidity area like the east coast or Oregon where there is very humid conditions the desiccant will have a shorter life than in a very dry area like Arizona.
Take into account thr dryer purges the desiccant chamber with each cycle of the air compressor, so if you have a lot of air leaks creating more air demand on the compressor the resulting extra air flow with also shorten desiccant life.
But for the most part with motorhomes the average usage isn't in rainy wet air and with limited miles each year the desiccant package should be good for about 5 years of normal use and probably more .heck I've seen 20 year old coaches running the factory installed desiccant filters and still working fine not that id recommend that.
The tell tale of a bad desiccant filter is excess water buildup in the tanks.
The danger of leaving a desiccant pack too long is that the desiccant will eventually plug up and bust it's container with in the filter which allows the many small beads of desiccant to travel into the air system creating problems with valves and components (a bad thing ).
Hope this helps
