Can't speak for the S-10. But, I know on the Jeeps, the airbags aren't going to go off on the trail, unless you really fawked up.
They only go off on a 26mph or greater front impact. I heard they told someone to go out with a XJ? As long as he didn't hit anything head on, he could do what he wanted to it to try to make the airbag go off. He slapped his helmet on rolled it multiple times, etc. no air bag, back at the lab, rammed it in to a wall and it deployed.
If it were jeep... I'de leave them. Most modern airbag systems require multiple sensors to go off before deployment anyway.
