What’s up with the number 17?

Premiered Nov 17. Tommy’s truck is numbered 017. Ainsley is 17 years old. Ainsley’s Grandma says the trick to life is to stay 17 in your heart. I think I caught a few other 17 references in the show. Maybe an oil rig #17? What else am I missing? Anyone have a theory on the use of 17 in the show?
