Coin door boxes are not the best place to hide things unless your locks are uncommon. So many people have #700 and #1382 keys. In past years I had a nice place to stash a duffle bag full of stuff. This year I don't have that luxury but my SUV will be in a covered parking lot. If I need some kind of uncommon part then I can just go 5 miles home to Plano to grab it. In my SUV I will have bare essentials like extra rubbers, bulbs, glass cleaner, paper towels, Craftsman digital leveler, microfiber towels and a socket set. Watch your socket set like it is your first born unless you feel like buying another set after the show.
