We looked into auto levelers for our 24F on an E450 chassis. HWH and Bigfoot are available and rather pricy. Especially when installed.
We bought a LevelmatePro sensor for less than $150. We mostly boondock, so rarely in a level campsite. We drive in to our selected location, read the Levelmate app on our smartphone that gives the inches to raise each corner, place blocks accordingly, drive on, slide out and stabilizers down. DONE! We have a 3' x 20' slide that tilts the chassis when slide is deployed. The LevelmatePro compensates for this when you do the initial setup/calibration of the sensor.
A couple sets of lego blocks and a Levelmate sensor for less than $300, beats an auto leveler system installed for $7,400 quoted to us. $7k goes along way for fuel.
