I have a 2018 THOR Siesta 24SS and just ordered an equalizer leveling system (quad) and will have it installed in 2 weeks. I looked at the HWH system before going with the equalizer. The equalizer system does not use the large springs to retract the rams like to HWH system uses. Both systems "bolt" on as required since the chassis is a Mercedes Benz 3500 Sprinter. No cutting or wielding is allowed. My coach came with electric rear stabilizers but I need the leveling system to bring the front end up for comfort. Not a cheap item. So far I am very happy with the coach.
