I've hit my diff, I haven't hit my front bumper. I figure in a "crawling" mode I'm not going to damage the radiator.. Once I'm on an obstacle all the other stuff is in harms way and I don't have as much control over speed as I do for first getting the front end up on top of it. Just some more justification for how I wheel and my reasoning.

I don't forsee anyone saying "I'm right you are wrong" but just in case this is going to be different for everyone and they should just read examples of what others have encountered and make their own judgment call on what is right for them.
