Ultra-Fab Power Twin II stabilizer jacks?
Have been toying with the idea of upgrading to the Power Twin II electric stab. jacks instead of using the Lippert ones. The Lippert ones have waay too much flex in them for my liking. If you look a...

I found on mine, that if the rear stabilizers are lower more that 3/4 the way down they are not as steady. I carry 2 8X816 blocks to put under them, and it helps a lot.
THat was the case with the scissors jacks on my old trailer. But these new electric stab jacks have a sort of A-frame support that comes down with them. IT seems to make them a lot more rigid. So far I've just needed to use my 10x10 lumber pieces when the ground is soft.
Even on uneven ground they work without blocks. According to Lippert it somehow senses the pressure and adjusts each side individually so they exert the same pressure.
The Lippert system makes it impossible to rack the frame.
The "C" channel cross piece rides inside a slightly larger "C" channel. When the first leg hits the ground, it stops lowering and the motor continues running while the inner channel , motor and screw drive slide inside the larger channel, and the opposing leg lowers until it hits the ground. Both legs then raise together maintaining equal pressure between them.
This system is IMO the best available. While it is not perfectly stable, it is VERY good. Much better than the other older systems.
The original screw jackstand jacks are of course the most stable, but they do have drawbacks in ease of use. Especially when boondocking on soft ground which often requires restabilizing every day or two.
