My 2018 Thor Siesta 24SS came with stabilizers which are electric with a push of a button on the control panel. They ONLY help keep it stabilized while parked. I had The Equalizer Hydraulic Leveling System installed at a family owned/operated rv shop. They were not cheap but work great. It keeps the mh level while parked at a push of a button or your can operate it from your smart phone. As an added bonus the leveling system can lift the entire mh off of the ground in the event you need to change a tire. I would only do that with additional support from a jack or jack stands for safety. I never use the electric stabilizer now that I have the hydraulic leveling system.
