I have the electric stabilizers and never used them. They only stabilize when parked to keep the rocking movement down. I had The Equalizer System installed at a local r v family shop. They work great. Just about all of the systems out there work(Big Foot, HWH and The Equalizer). The price depends on the options you choose. Manual mode only or automatic, Blue Tooth... Do some price comparisons. In a pinch, you could use the hydraulic levelers to lift a flat wheel in order to change it. I also carry a small bottle jack for safety whenever I need to raise the wheel for repairs/maintenance.
