Homeowner here.
Here's a brief list of things I've done with my truck this year that would be difficult or impossible in a car:
I mean, the list just goes on and on.
Yea there are alternative ways to get a lot of this stuff done (delivery or truck rentals mostly) but these get expensive and time consuming to arrange, not to mention they can be a huge headache for specific scenarios (like the move to a new house leaving you between houses for a week in the middle).
Any homeowner automatically has a ton of uses for a truck.
