I have a 2018 THOR Siesta Class C coach and recently had the Equalizer System installed on it. The system comes with a bluetooth operation for your smart phone. It works great. I had it installed and it took a couple of days. It isn't cheap but I think we will be very happy with it. It has 4 rams that each lift 7500 lbs (total lift 30,000 lbs). The system costs about $3500.00 plus installation. If you are handy, you can install it yourself. With my coach (Mercedes Benz Sprinter Chassis), I had to have it bolted on with no wields or it would void my warranty. It comes as a complete kit with everything you need (except transmission fluid for the hydraulics).
