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?
