Good question! The first M2 chassis Senecas with air brakes (2016 - 2018) did not have an air dryer as standard. Some owners have taken it upon themselves to add one.
I believe the 2018.5 - 2019 units built on the S2RV chassis did come with a factory-installed air dryer. But I don't know if Jayco is still specifying an air dryer on the 2020 chassis. My 2014 M2 with an Allison 2500MH transmission came with a dash overdrive lockout switch, but they eliminated it several years later. So Jayco does switch things around on their chassis without notice.
Maybe someone with a new unit can let us all know.
