I am in the lower 48 trapping an area of about 508,000 acres of trails/2tracks with very limited maintained roads. What do you all carry in terms of survival kit to keep yourself going if something happens (break down ect)

Last week I was out and my 4wheeler quit on me several miles from the road I dropped the truck on. Fortunately it is still warm down here making it a pleasant walk back not the -20 to -40 it will be in a few short months, and I was at the top of my line not 15-20 miles down further..this event has given me some pause as to what I keep with me.

More important than any tool is to have the clothes readily available to withstand the worse weather you can possibly encounter. Then I'd argue 2-3 means of lighting a fire, The mini road flares are awesome. A mora knife, a 2 quart pot, first aid kit, some cordage and a synthetic sleeping bag.

I like Mors kochanski books. He was a Canadian cat and has the cold dialed in pretty well.

well said

#1= means of communication.
#2= means of communication.

#3= fire-making tool.
#4= water that is not frozen.

The rest will depend on your situation and problem. Your machine of choice should ALWAYS carry basic tools and parts specific to that machine.
A small shovel, (those folding ones can do a lot of work and take up little space), and some jerky or pep sticks stay good if wrapped properly, and are usually in a pocket of mine, anyway.
Again, the most important tool you can carry is a reliable way of communicating with somebody that can help.

Road flares are an excellent firestarter, I've never seen the mini ones but have packed the regular ones for years. A spare set of dry clothes is something I packed for years on the snowmobile and need to get back into the habit of. Shovel, winch or ropealong to get your machine unstuck or back upright, and an ax. A chainsaw is great, but an ax is more reliable, if I figure on needing to cut blowdowns out of the way I carry a saw, but an ax is a permanent fixture on my snowmobile. Not sure where you are and how much snow you have, but if there is enough to run a snowmachine you should have a pair of snowshoes strapped on it.

Everyone's situation is different. You need to taylor your kit to you and your surroundings. Let's use your last adventure as a base. You said you had to walk a couple of miles back to your truck. What would you want with you on that walk back? Put it together.

Now, like you said, what if you had to walk 15 miles back to the truck at -20 below with a 20 mph wind. What do you want with you on that hike? Put it together with the other stuff.

Now, what do you want when you get to the truck? Put a truck kit together. Put in a Hide-A-Key, it's a magnetic key holder.

Lastly. Fill your pockets with whatever you think is necessary for your walks out. Sometimes all you have is what's on you. I suggest at least 3 ways to make fire. Compass and blah, blah, blah.

My kit for trapping will look a lot different than yours. Mine is taylored to riding a snowmachine without cell service. My compass works and so do my zippo lighters inside my parka. That and a working brain that doesn't panic and does not give up will get you back to the truck.

If you still are not sure what to pack. Spend the night in your backyard under a tree with a pad and paper. You will have a great list by morning. One or two of them written over and over. Pack those.

Get rid of all the comfort stuff. You are not camping. Want to read about other people failures. Read "To build a fire" by Jack London. Might help you pack your kit.

Good advise there !

"Put a truck kit together. Put in a Hide-A-Key, it's a magnetic key holder. "

NOT a Hide-A-Key!!! I can't count the number of those I have found over the years walking along logging roads, and most of the roads I'm familiar with in Wyoming are rough, a magnetic Hide-A-Key won't last two days on them before it bounces off. What I do is use duct tape and tape a spare key up underneath the bed rail on the pickup, or on a flatbed (or if you aren't using a pickup or have a locking canopy, etc.) wire a key somewhere on/under the truck. That way it is still there when you need it.

Otherwise Super Wide's advice is spot on, and the advice to have a spare key hidden on the truck is excellent. I have helped a number of people "break in" to their rigs over the years when they either didn't have a spare key, or it wasn't there when they went to get it. You can break into most modern rigs with the radio antennae much easier than you probably think, but it isn't something you want to do after a long day when you are cold, wet, and tired.
