Those scissor jacks are stabilizers only. They are not intended to level the trailer. Level by using boards or blocks under tires for side to side, then tongue jack for front to back, then the stabilizers just snug against the ground. Using any stabilizer jacks for leveling can cause major issues or damage. Doors won't open, slide outs won't work etc etc.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
