Did notice hydraulic pump was leaking a little bit, the research I did today told me lippert had recall on these pumps because of bad o ring issues. Was wondering if this would cause slide not to go in, agree on not leaving slides out, local dealer said the same thing. They told me I have two hoses that run the ram in and out, my reservoir is half full. They also told me that my battery and converter are good, if other two slides go in then, then this isn't problem. Like always, manuals give very little info on these issues. I also have switches in compartment that turn off slides, will check to see if it got turned off while winterizing.
