Say Ken, do you have any pictures of your Liberty you want to put on the web, and post a link here? I think that that would be helpful.
It is because you were an idiot and expected the Liberty to have some magic ability to compensate for your lack of driving ability. No matter what kind of vehicle you are driving, you don't drive over things that are big enough to rip stuff off the bottom of it. You don't even do this with a Cat D9 'dozer, unless you want to get high centered, crush your belly pan, and have the other 'dozer operators make jokes about you.
Lol, we are not all blue collar people, raised as grease monkeys (except maybe Nathan and Bill ;o). We are for the most part sensible people who got into off roading gradually. As in anything, you have to walk before you can crawl. Most of us who go off road started off with logging roads, beaches, a pasture, or "beginner" trails, drove around there a bit, and bit by bit moved up to more difficult terrain. When we get a new vehicle, we test it likewise before taking it to the big boy trails, and when we get there we feel our way, slowly, until we are used to the trail and how the rig behaves on it. It takes some skill to drive on the more difficult trails. Heck, it takes some skill to drive on a graded gravel road. It is like anything else; if you attempt it without the skill or with the wrong equipment, you are going to get hurt or break something.
You have the opportunity to learn something here. If you seriously want to get into off roading as a hobby, you now have some information that will let you approach it in a more intelligent manner in the future. If you want to behave like a spoiled little boy who broke his new toy on the first outing because he had the wrong toy and didn't know how to use it, you can blame everyone else for your problems.
No where is it pointed out that a Liberty is not a Cat D9 'dozer either. What an idiot.
