2014 Keystone Alpine Hydraulic Jacks 6 Jack System

Thanks for the information. Upon further review I went underneath and the underbelly is sagging a bit which looks to me as if there is a hydraulic leak at the end of the living room slide which is hydraulic. Do not know if this is something I can fix or not. Do any of you have any advise as to how I should go about this. Thanks again for any input.
