Make sure your jack in the vehicle is actually useful for your vehicle, buy a heavy duty jump box they are the size of a old Gameboy make sure it's a USB c rechargeable I buy everything for my vehicle that I can charge while driving. My jump start sits by my driver seat so I never forgot to charge it and I'll rotate what I'm charging for the drive that day like head lamp, jump pack, drill batteries which is really for my work but useful. And road flares are really useful if you know someone is coming for you and are so close saves so much hassle and flashlight works but you notice them easily with all the other headlights. Metal tie wire in the concrete section, leather gloves. To tie up broken exhaust or whatever. Also electric tape and vise grips IV had to pinch brake lines and tape the vise on before just to get places before just drive really slow and avoid braking. IV driven very overloaded box truck for over a HR before doing this but with extreme caution this is for very very odd circumstances
