I live in the coastal mountains and any flat spots on my property have buildings on them. Having said that I have gotten myself in off camber situations or just having a tire drop off an edge or into a hole. When this happens you put on the brakes ASAP. The stock differential lock requires you take your foot off the brake and use your heal to depress the differential lock. I have added a lever so I can keep my foot on the brake and use my left hand to engage the differential lock. I certainly don’t get myself into these predicaments on purpose but when it does happen the lever makes it safer to get out of them.
