That JackPack looks interesting. I think my jumper was an S-Type from Costco. I had an air compressor for over 25 years and just finally replaced it. One of my friends in Tahoe got the TPM light for 2 tires last winter and I needed it for a tire the next morning. May I suggest adding a reflective vest? Also for changing tires, a pipe extension for the big ratchet or an extending tire iron for more torque. Changing tires sucks enough. My kit also includes stuff for blizzards or the middle of no-where items: toilet paper, wag bag, water/food/cooking fuel/camping pot/4-season stove, shovel, snow saw that can cut wood, too, tire chains, warm gloves, hat, little blinky lights, reflective triangle, headlamp, mini first aid kit w/ blot clotting stuff and tourniquet, and I seem to have 2 tow ropes.

So many pliers

man your car is less expensive than your iems lol
