That was my approach too, until i made this purchase. It came this way , i had no choice and would not have spent the money on them.
They did hang too low, the rears, the fronts are fine. I had to cut the mounts on the rears to tuck them a little higher into the frame. They have been fine since. It is one more thing to go wrong though.
I like the manual mode to be the better option over the ‘auto mode’ to level it. The auto mode makes the entire rv too high, creating a tall step in and out.
I still carry blocks with me, you never know with this quality gadgetry.
