Only had the rig for a month now and have a couple of questions. I see that there are multiple holes in each of the rams that I assume are for adjusting the distance for ground clearance? I have a low spot that the rear back jack extends to full and just barely touches the ground. Have to add a couple 2x12 blocks to give it enough room to adjust. Just curious if anyone has changed theirs and if so, why and was there any issues from it? Or should I just leave it alone and continue using blocks when necessary?
