Just a thought about the unlocked RV before turning in for the night. If Westerfield was so anal that he called his son to check whether the front door was locked on his home then how could he ever have left the RV unlocked ? He even had passwords on files on his computer and lived alone didn't he ?
He would apparently be the type who checked the locks on his RV at least twice or is the theory that his girl friend left it unlocked ? If he called his son and made him go check wouldn't he do the same for his girl friend ?

I already have a short name for the other club.
