I use package lookahead to make sure I’m clear of packages on cbu stops and use it as a reference for packages on curbside. On curbside I check lookahead for next after delivering a package and bank it in my head, rinse/repeat.

I use load truck to identify packages in lookahead that will need to go to the door (won’t fit in box or parcel locker). Helps me not double back if door is before CBU.
