The standard Lippert stabilizers so many TT have do stop almost all up and down movement. However they do not stop side to side movement - rocking - caused by the TT springs flexing as weight moves from side to side of the trailer.
I've used Bal Loc-Arm stabilizers on both my TT (the same ones - I installed them on the first trailer and moved them to the second trailer) and they stop almost all movement.
The Bal stabilizers provide a 90 degree offset from front to back. I haven't had the ability to set one to go across the TT.
Steady Fast does the same thing - but emphasizes a cross-trailer arm. Which IMHO does a great job. It works really well between the front two landing pads of a 5th wheel.
I have several friends who have them and love them.
No, they are not electric. They are mechanical supplements to your existing stabilizer/ leveler system.
The existing stabilizers deploy normally - then you tighten the friction lock on the Bal Loc-Arm or Steady Fast to lock the mechanical arm in place. You must loosen the friction lock before raising the stabilizers.
Your TT / 5er is designed to allow movement in three directions between the ground and the frame due to the springs and shocks (1 - tilt up and down from to back, 2 - vertically up and down from bumps in the road, and 3 - side to side rotational movement as weight shifts). Normal stabilizers only minimize / stop movement in one of those three directions.
As mentioned above - the stabilizers work best if they only have to extend a short distance - blocks do help. Another thing to help a lot is a jack under or near the axles to take weight off of the springs. A pair of supplemental scissor jacks really help.
Another point to remember is that all stabilizing systems have a little 'play' in them. And if you are not setup on a firm concrete pad, you may find a lot of slack after a day or two.
We setup today in an RV park with grass with a little gravel for a pad. Fifth time our Good Sam group has been here in four years. I know from experience that my blocks will sink a bit in the ground, and I'll have to adjust the stabilizers and levelers every day or so.
