Hydraulic Jacks.
Hi Jack:
In a word, NO! The jacks work together, one side comes down, then the other and they both lift the front of the trailer evenly.
As for the Electric Jack in back, it is on Screw system. Not independent, both sides come down at the same time.
Would be nice to have independent jacks in the rear of the coach to help level the unit.
Take Care.
