Sounds like you keep a pretty complete kit, I have a couple of additions. I have one of those white tool boxes that go across the back of your truck, I have only my no kidding E-kit stuff in it, and believe me it's stuffed. I'm not going to disaggree with you on anything you carry, but I carry two cases of bottled water under the tool box and two cases of MREs. Yeah it's extra weight but I live in AZ and water is essential and extra MREs give you the extra time to assess your situation and devise a plan in a uncertain situation. You may have water readily available so the extra water may not be necesaary, but having food to cover you for several days may be an option you may want to consider.
