Full extension of landing gear making me nervous

Just as a follow up on my original post. I made some 12x16 landing pads using three pieces of 4x4x16 sandwiched between two pieces of 2x16x12 on top and 1 2x16x12 on bottom. Once in place under the landing gear and plastic blocks were under each of the stabilizers, the Level Up system was able to level the RV with no problems. The hand made blocks are now a permanent addition to the RV. If not needed to level the RV, they make great entry stairs!
