Not a six-point, but we just added the Ground Control 4 point system to our ElkRidge. The Elkridge does not have hydraulic anything. Ground Control replaces your two legs with independent electric jacks in the front, and adds two electric jacks behind your rear wheels. You still have your rear stabilizers as well, so six points of contact.
This was a fairly painless install, though it took about 2 days.
The benefits:
No hydraulics (so no potential leaks or popping), easy to self-install, cheaper than Level-Up, independent jack operation for leveling or move all together, can use to change a tire, remote controlled.
Drawbacks:
No auto-leveling feature.
