Personally I am not a fan of auto levelers. I have seen many cases where the coach is set too high or wheels are off the ground cause the so called "auto" part was trying to level the coach. You might find it better in these cases to level it manually. If you are on anything but cement or asphalt, I would use wood and not the linx levelers. They can break pretty easily on uneven surfaces. You dont want the rear tires to be off the ground, so if your back end is too low, run the tires up on wood or the linx system to reduce the lowness. Then you can use the jacks to finish off the level as long as they dont raise the tire off the ground.
If the front end is the low area, you can put extra wood or linx levelers under the jacks and raise those tires off the ground. Again, I wouldn't raise them way off the ground but several inches or so is fine. If the front end is way low, drive the front tires up onto some wood and then use the jacks to finish the leveling.
