Sometimes it is a hard thing deciding what to do with something that reminds you of someone but think about what your Dad would have done with it.
My thought would be to decide if you need it, want it or just plain can’t stand it if someone else is driving your Dad’s Truck, then make a decision on what is the correct path for you.
I always believe once you have taken time to think about and make a decision it will be the right one for you and if you do sell it then some one will be getting use out of it instead of seeing it sit there and rot away.
If there is a need to keep it then you will find a way.
Sorry for your loss, think hard and your Dad will help you decide.
