Jack; I have never seen or heard of those stabilizers sorry I am sure someone will make a post on them.
When we had our coleman pop-up I never had trouble securing it. After leveling left to right I would block both wheels in front and back and then Level with the front jack afterwards getting all 4 stablizers down just barely making the camper move as I tighten them and it never moved. I have done the same on both of the toy haulers and they don't move either. A thought is your not putting the jacks on wooden blocks they could let you move too,if I needed more room I used Lynks levelers because they locked togeather. Hope this all helps.
