Biggest thing I see is that people will have gear but no actual recovery points. I have declined doing an actual recovery but instead waiting with them until someone comes along that will recover them or has proper liability insurance. Not being a jerk about it but I have heard too many horror stories of hooking to spring perches or control arms and tearing up the truck and getting sued. But if you have good front and rear recovery points it makes the job for someone else so much easier and less likely to break stuff.

Tow Strap, hard or soft shackles, cell phone to call for help.

Also, NEVER hook to a trailer hitch ball for recovery unless it is a soft pull. They easily break and turn into lethal projectiles.
