Have a 2015 Landmark 365 Key West with Lippert hydraulic leveling jacks. One jack, door side in front of tires, goes down when autoleveling. It will make contact with the ground and then seems to stick there. If the coach needs to rise a bit on that side, the jack does not go down any more - it stays at the same length resulting in it being off of the ground. I have tried leveling blocks under it thinking maybe it was maxed out and that doesn't change anything. Dealer has run tests for hydraulic leaks in cylinders, checked the hydraulic switches and can not find the problem. I, and the dealer, have spoken with Lippert and followed their instructions, all with no results. Wondering if anyone else has had a similar problem and what you found out. TIA.
