A lot of people underestimate the huge forces involved in recovering a vehicle. Make safety your first priority. There is a vast range of recovery gear available. Ensure recovery straps are rated (the norm for 4WDs is 8000kg) and have a stretch of around 20%. Use only rated tow hooks or D shackles and ensure attachment points on the vehicle are suitable for recovery purposes. Never use towballs as an attachment point, they can shear off and make dangerous missiles.
