A stove, some propane for the stove and a cot aren’t much in the way of camping equipment and don’t qualify as survival gear by any stretch of the imagination.
The way I sees it is this:
A) The burning of the truck was a part of some plan—The broken axle was a misadventure—and he had to hike to where he had a jeep stashed.
B) He had help—a second person who came and got him.
C) He carjacked someone and they are off in another state.
D) he has doubled back for his final showdown with the LAPD. Look to see this in the next few days.
OR E) he’s a fool and has frozen to death or has hidden in a cabin and will be discovered, burned out and shot.
Agreed this is what you take when you go car camping in a state park not when you are in a Escape & Evasion scenario.
This gear got torched in an effort to destroy any evidence of what his plans are for getting out of Dodge.
