You forget the timeline involved. There is nothing surprising about getting stuck 3-4 times on dirt roads over the course of 19 months.

Sure. Wouldn't most people dig themselves out?

This is a "10 tonne truck" we're talking about. They also mention how once they needed 3 trucks to pull them out.

Probably you have never experienced a stuck heavy vehicle. It's usually impossible to get one out without assistance.

Rarely, you may have a winch and can anchor to something which can support the vehicle's weight, but certainly not 'dig yourself'.

A winch that can pull the truck seems an essential item to take, but your general point stands.

Also, perhaps, don't drive a 10 tonne truck?
