I have only had 2 coaches with a leveler system, and one was manual, the automatic Hydraulic system on my Alante seems to have a glitch, not sure. When I level the coach on either manual or auto most of the time it leaves the passenger rear jack up in the air, sometimes only a few inches and at other times a foot. This leaves the coach on a tri-pod stance which cant be good, either for stability, or alignment of components. I can force the errant jack down by going to manual and hitting rear jacks button.
I liked my fully manual Quadra system much better as it was power in/out 2 jacks at a time. This PowerGear system is 'Jacked' so to speak, if you go a bit to high up and cant compensate with the other jacks you have to retract them all and start over, very bad design.
And yes, I lower both the front & rear for a 3" lift before leveling on manual, just as the book suggests. Any suggestions??
