I've been stuck on I-75 unable to get to an exit when it was shut down because of a serious accident. For a few hours maybe, until the casualties and wrecked vehicles were all hauled away. But nothing long term. I saved the PDF as Alf's Car Kit so I can look it over more later.
I put half of my Storacell battery caddies (no 9 volt) in the Mechanix Wear Small Black Roadside Bag I keep between the second row bucket seats of my Yukon. The third row seats are in my living room, so I have someplace place to sit and some room in the back of the ute. Now I have 6 AAA, 4 AA, 4 123A, and 4 18650 batteries in the vehicle at all times. The 4 C caddy has 3 lithium 3.6 volt 26500 batteries, 1 for my Tractor Supply Co. flashlight, and 2 for my 2 C cell Maglite that I took the krypton bulb out of and replaced with a Nite Ize High Power LED Upgrade. The remaining spot in the caddy holds the 4 AAA battery holder that's supposed to go in the TSC Flashlight. It's too long to stay in place so I put a couple of pieces of electrical tape over the top. I need to get some 2032 batteries and toss a couple of them in too. I'm going to throw a pack of 3,600 calorie S.O.S emergency food rations in there too. They're made of stuff that doesn't make you thirsty, so they're good to take as life boat rations on the ocean. There are 9 410 calorie bars per package, 3 a day for 3 days, and I bought 4 packages. I think I can fit a whole package in there with te stuff I already have, and if not, I have 6 left in the package I opened. I have some free Harbor freight flashlights in the car too, in the glovebox, first aid kit, and front door pockets.

I threw away the expired pills from a few individual/car/home first aid kits, and put the remaining contents in the bag, along with a pair of EMT shears and a roll of medical tape. My NOCO Genius battery charger sets on its side in the bottom of the console between the front bucket seats, and the first aid kit lies flat right next to it. There's just enough room for them and a pair of lightweight fleece gloves, and the console organizer tray sets right over top of them, with room for CDs or whatever on one side and a small cardboard box I fit to the other side. That has a plastic grocery bag in it I use as a litter bag that's completely out of sight.
In the back I have a 24 gallon Rubbermaid Action-Packer Storage Container the same size as a 48 quart cooler. I have a lug wrench, jumper cables, tow strap with a big clevis to hook it onto things, tire plugs and a small 12 volt compressor in the tote. Along with various camping gear, like a small bow saw, 2 machetes (the 12" sucks and 18" rocks), tomahawk, paracord and rope, etc. What I don't have is food and water, or any clothes other than the fleece gloves and a pair of Mechanix Wear Leather Cow Driver gloves. These things are so soft and supple they feel like elk or deer. They're water resistant yet breathable, and on sale right now. When mine got dirty, I washed my hands with the gloves on and after I rinsed them off, I stood them up on sticks to let the air circulate in and around them. They're still just as soft and comfy as they were new. I have a big bow saw, ax, and a shovel next to the Rubbermaid box since they're too long to fit inside. The shovel is an entrenching tool blade with a T shaped handle I made of 3/4" pipe and welded on. It's about 3 feet long and lops of green tree branches better than either machete or my ax does does.
