Once again, Thanks for the ideas. Its Great to draw from professional experience. I am by no means an expert.
I wanted to keep the kit small enough to keep in the front of my truck in the console, so if I am the one in the accident it is within my easy reach. If I am hurt it would be very hard to crawl to the back of my quad cab to grab the kit from under the rear seat storage bin. Weight is not an issue as I won't be carrying it, but size is. I didn't add any gauze as the shell dressings appeared to be enough, and to keep the size down. There are some items that are always stored in the truck such as an LED headlamp, duct tape, gloves, etc which would always be of use. I don't have a safety vest but I always have road flares. The quick clot and C-A-T tourniquet I use because I have training to use them and I can get them, along with the shell dressings and triangular bandages for free. I hope to never have to use quick lot on a stranger though, especially if it was a child. I have seen a hard core soldier bust into tears and scream at the top of his lungs when the Medics had to close a wound with quick clot.
