Fixed routing is the easiest to work with. Use block heater year-round, investigate right-turn-only routing (as UPS and FED-EX do) or routing that is longer but is non-stop, etc. Where & how to park . . ton's of details that we learn to integrate and make from them new habits.

Start with records. What matters is any change to baseline mpg, so record all miles and all gallons. The percentage change to that base is the road to improvment.

Second is mechanical baseline. 4WD CTD's tend to have sloppy steering and front end looseness. Fix these things. Bring all book maintenance to date. No CAC leaks, etc. New shocks, etc.

When it's time for tires, consider better quality that also lends mpg help. Tread design is the big thing. Rolling resistance is the big thing for around town + commuting once warm-up time has been shortened / addressed.
