Need For Leveling Jacks??? Please Help Me Decide

As a solo traveler, I wouldn't be without them. Mine are HWH semi-automatic. When I turn them on, they extend until all four are touching the ground. Then a light comes on to tell me which button to push, either front, back, left or right pair, until that light goes out. then the next button until that light goes out and I'm done. Trying to level in a pouring rain just once, makes them worth every penny.
