You need to talk to the folks here for actual K5 buying advice. As alluded to in my last post, and my screen name, I tend to run Fords.
And I know about no trees.
Every four wheel vehicle I have ever owned had a PTO winch on it. So, after I had to walk out a couple of times, I learned to drive towards trees. If I saw a bad looking hole with a good solid tree on the other side, I would go for it.
If there was nothing, I would turn around and go back.
However, I came up with a plan many years ago. I live on the coast, and my family has a seafaring background.
One day, I borrowed a Dansforth anchor from a friend's boat that was in for repairs.
Got a friend with a winch to follow me, and drove off into a hole I had never tried before out next to the bay.
Sure enough, I got stuck.
Walked out through the mud carrying my cable and that anchor.
Hooked the cable to it, and set the flukes in the mud.
Started winching. The anchor slid towards me a little then started biting in. Went down a short distance, and then the truck pulled out.
I figured I had it made.
Until the next bog hole.
That time, I got stuck big time. Hooked up the anchor, and pulled myself out.
Then could not get the anchor back. The mud was soft, and the pull hard. I think it went about 10 feet down.
I could not get it up with the winch without breaking my front suspension. I actually pulled so hard my rear tires rose off the ground.
Finally had to saw the cable off and go home.
Went back a couple of weeks later with some help and shovels and dug it up.
I could have hooked the cable like they do on boats, to the back end of the anchor with some rope holding it to the front.
Then, if it gets hung, you pull at an angle and break the rope. Then the anchor backs out.
But the whole exercise soured me on the idea.
Later, someone else who had more sense than me figure out the trick and invented this.

Never used one, but I hear they work ok.
Surely someone here has and can chime in. Of course, this place sees a lot of rock climbing, so maybe not.
Doubt its much help in granite.........
