Another option to consider is the Ground Control system. Four independent 5000 lb. electric jacks, easy to DIY install, no hydraulics to leak or worry about, no computer to go brain dead, and way less expensive. Granted, it is not an automatic leveling gizmo, like the Level-Up is (when it works), but easy to achieve level all the same. Should one of the motors fail, you can swap it from another jack or operate it manually with a ratchet and hex bit. You need to take your rig to Indiana (or an authorized service center) to get the Level-Up installed. The Ground Control system can be shipped to you.
The Ground Control system must be good since Lippert bought it from Reico-Titan and sells it through Mobile Outfitters.
