In the lower 48, sometimes your main danger isn't the wildlife, but humans. Here in WA state I have found discarded propane tanks, clear hose, beakers and other glassware etc...all the usual makings of a Breaking Bad operation out in the woods...at the end of little-used Forest Service roads. Now these folks are seriously dangerous because you can go to jail for many years for making that stuff, and the operators might just shoot first and forget the questions entirely. If you pull up on something like that, you should just turn around right away and leave with haste. But there are other practical things that are more useful and you would probably need more than worrying about bears or meth makers.
I always carry any spare belts I replaced, the old ones, and a good tool kit. Two spare tires is a good idea, along with a tire plug kit and a pump. I went out in the hills above Naches, WA once and found out it WAS possible to get two flat tires on the same trip. Using the plug kit on the second flat, I still had to shove a bolt into the hole on the tire (pretty big hole) and made it back to civilization. Slowly.
Recently, I picked up the item shown below and an Amazon return 50 watt solar panel and ditched the little gas generator I was using previously. I gave it a five star video review at Amazon. This one even beats the Jackery portable power units. It uses not just a lithium battery, but the LI-PO 4 battery, which will take many more charges than straight lithium and is far less dangerous. But it is a heavier unit due to the lithium iron phosphate battery. However, this unit comes with a nice little zipper case that includes the charging connectors for wall power, cigarette lighter, AND solar panel. It also comes with a built-in MPPT solar controller, if you can believe that. So you can plug a solar panel of any type right into the thing and it will stop charging automatically when it's full up. I personally recommend this 300-watt hour unit. Last trip I took was a group campout north of Rainier and the group generator stopped putting out power. Still, I was able to run a Samsung 32" TV and a small DVD player from this box and watch two complete movies...ran it down only to 40%. That's pretty good. LI-PO 4 battery will also give you full power right up (almost) to the point where you need to recharge. Some units get fading power and the cheapies that use a bunch of strung-together 18650 flashlight batteries aren't worth your time. You get one or two bad batteries in that series and the entire unit works much less.
Here is the link to the unit at Amazon. Currently it is 265 with a 50 buck off coupon. You will never be sorry with this one. https://www.amazon.com/gp/product/B08GPL38M3/ref=ppx_yo_dt_b_asin_title_o09_s01?ie=UTF8&psc=1
