I should probably add a reflective vest. That's a good idea. At home, I've got a pretty good adjustable rolling stool I picked up at Harbor Freight. Has a tray on the bottom with a magnetic pad where I can set all the nuts. Wasn't sure it was going to be worth the $110, but it's proved itself on a lot of jobs. It's been great for lawn mower servicing and the like. I like that it has a little back to the seat. Adds some stability. https://www.harborfreight.com/professional-adjustable-shop-seat-with-tool-storage-black-58658.html I also just ordered a couple collapsible stools off Temu. Probably junk, but it was under $20 for two of them including shipping. If they work, great; if not, I'm not out that much. I wanted something that would fold up really small so I could tuck it into one of the side pockets in the cargo area.
I love that set up except for the need for the battery to be charged. Life doing what it does, when I have a flat I will also have forgotten to charge the wrench battery.
I use Ryobi tools, so I have a bunch of batteries. And they've got a button to press to see the state of charge. I check every once in awhile(maybe every month or two) and if it's less than 4/4 bars, I swap it with one of my other batteries. I use 4Ah batteries for this, so even at half charge they still would have enough juice to do a full tire rotation and completely fill a couple flats. You don't want to get stranded unprepared in a bad ND winter. The cell phone changed everything, but I grew up pre-cell phone when at least a few people died every winter from getting stranded on the road. What really drove it home to my generation was a family of four all dying inside the city limits of Fargo on a major street during a snowstorm. They got stuck going under a railroad underpass and let the exhaust pipe get covered in snow(even though they cleared it at least a couple times). Carbon monoxide poisoning.
I got a donut for my Gen 5 but I suspect I'll be calling roadside assistance to install it if I ever need to, unless the car's in the driveway. It's not that I want to avoid the physical effort. It's that I find the idea of mucking around the side of the road while cars are zipping around very unappealing. Also, it rains a lot around here and working in the rain is no fun.
