The stuff I brought outside of the obvious gear, clothes, etc...
-tow strap. Didnt need, but glad to have it. I have needed it since, and it now stays in my tool box
-normal size wrench/ratchet set. Didnt use for emergencies but was useful at camp a couple times
-My impact drill and charger. Not needed for emergency but did use it a couple times
-Jump box/air compressor combo. Found it on amazon. I dont go anywhere without it anymore. Didnt need it hunting but have used it more than I ever would have thought since then. Great little thing to leave in tool box or under seat
-Tire plug kit. Not needed, but smart to have.
-Fuel can. Not needed, but peace of mind on long stretches where you dont see civilization for hours.
-big roll of gorilla tape. used that way more than I thought we would have
Other than that, it was just normal stuff I pretty much always keep in the tool box or under the back seat. The one thing I would probably add next time is one of those hitch carrier things. We were able to fit everything OK, but it was piled so high it blocked even the camera on my digital rear view mirror. Not the end of the world, but I'd rather see out my rear view if its an option
