So I read on here don't use the stabalizers for leveling. But you put the stabalizers down on each corner, and level with the tires. But the tires are on springs and if I put the stabalizers down and then me and some other guys enter the camper. That could be about a 1000 lbs with would make the springs compress and the corners to hold the weight. I would think the best place to add a jack would be just aft of the tires? Please if I have this all wrong I apologize.
