Offroad and airbags... what is the deployment sensitivity?

So, I got to thinking after watching a meme the other day that showed a chev truck that had parked its self half way up a stop sign. As the driver backed off the post the truck bounced significantly and set off its airbags. He did not drop that far and it got me wondering, what is the line of banging around that sets off the air bags in our trucks?

I have read the manual and know that I can shut the airbags off; however, I know that in the real world I will forget to do this. So, what is the limit? Does anyone have experience or advice? I am planning some trips this summer out west to do some aggressive four wheeling in the Big Horns. Also planning a spring trip to Moab. Do all the people I am watching running Fins and Things shut off their air bags? My guess is no... the idea is to be slow and safe, but some significant bouncing can occur. What do you do?
