This may be the wrong subreddit for this, and it is, I apologize in advance. I'll also say in advance I'm not a professional nor claim to be. I have basic first-aid training through my employer (construction) and through a local CERT (Community Emergency Response Team) group.
Recently, I had to help my SO with her elderly father. Without too many details, he ended up witha cut on his foot. He didn't have any kind of bandages at his house, but I remembered I had a small FAK in my truck (A little JJ Keller kit that I took from a previous company vehicle before it was traded in... https://a.co/d/0fHtrPfN ). Everything was still sealed but some of the stuff had expired by a few years. I was able to get his foot fixed up and taken care of.
Which brings me to my new issue. I've been looking into getting a new FAK for my truck. I know Walmart and other places carry general kits which would probably be fine, but one thing is I drive roughly 90 minutes each way for work, usually early mornings or late nights. I also work construction, so there is that addition. I also do off-road trips (nothing wild).
I had a discussion with AI about a good, multi-purpose kit, and it was pointing me to something that almost seemed like an ambulance in a bag! The first one it recommended was something from Scherber - a Basic First Responder Trauma Kit! I'm not a paramedic! Sometimes AI can run away with itself...
I spoke with my sister, who used to be a paramedic. She told me that my brother-in-law recommended one of the marine FAK's, and he recommended one of Adventure Medical Kit's Marine 450 kit. I like the idea of it being waterproof, as this would be store under the back seat of my truck, or possibly in my Jeep (when off-roading), but $230 is a bit much!
My idea was to have something that can basically treat myself or someone else until professional help can arrive/take over. The cases I was using were either rendering aid for an auto accident, or something happens while out off-roading, or a natural disaster (hurricane, tornado, etc).
Thanks for reading and providing any constructive advice!
TL:DR - Looking for an upgraded first-aid kit (FAK) for my truck/home/Jeep that's more than just bandaids and tape...
