I've beem driving various GM and Ford diesels since 2005. I never put anything in the tank but diesel. These vehicles were all driven regularly so tje fuel was always new.
DEF will eventually expire. I would fill your tank if it's going to sit for months.
Diesel does not have the same characteristic as gasoline, particularly ethanol based gas which attracts water. It stays "fresh" for just about forever in a sealed container. You want to fill the fuel tank though as an air space helps to encourage the growth of bacteria and funguses which can play havoc with your fuel system. I use an additive which also discourages that from happening but it's not an issue if you are going though fuel every week.
