I’ve been looking for a picture book about a family that goes on a road trip (I think).  I remember the pictures being detailed, I think the family had a loaded up station wagon with many things tied to the roof.  They go to the beach, I think,  among other places.  I was born in 1974, , so it might be late 70’s, early 80’s?  The illustrations almost had a Where’s Waldo look to them, though NOT a find and search book.  I think there was a baby in the family, maybe three kids.  I remember winding roads and color illustrations.
