Im sure GrandaPa is glad its staying in the family.
Ive already told my son that if he chops our 50 when he gets it, he'll get a "time out"
He's only 3 years now. (It was his grandpa's truck also.)
Post some pictures of the truck when you get a chance.
Being a AZ truck it must be in pretty good shape.
This forum is the best
Good Luck
