So last night I took some friends for a ride in a field. The grass was low but there were patches of stuff that hasn't been cut yet. Come over a himp and say that would be perfect to jump. Put in in reverse and start backing up. Camera says everything is cool, nothing from the sensors. Back up about 20 feet and CRUNCH. Turns out there was a concrete block buried underneath some grass that actually prevented me from backing into a deep narrow ditch. High centered on the rear axle and used 4 high to get out. No noticeable changes in the handling on the way home. You can see the damage that was done.
