No problem with twist. The two front jacks are connected with a "T" fitting and act as one jack, supplied by one hose. They will distribute the weight between them, regardless of the chassis angle. If one leaks, neither will work.
Stack a couple 2x6 lumber under one of the front jacks, then lower the front jacks, You'll see what happens. Don't go so high that the jack without the lumber starts to lift off the ground.
You actually have a three point leveling system, one front, one left rear and one right rear.
