For at least 10 years now I have been intimidated by Lippert Power Gear Slim Racks and Hydraulic jacks on my last 2 WBGO motorhomes- seemingly always living in fear of a major failure while on the road where I could not get help.
Well no longer. Much to my relief Lippert has apparently recently(????- I've not seen this before) posted a whole series of instructive videos on repair and component replacements for many of their products. I had not seen these videos before and my You Tube site says they were posted 12 days ago (????)
Two possible failures that have always haunted me have been the potential failure of my Slim Rack systems on the slides, and the hydraulic jack system. The videos in the You Tube Lippert Technical Gear playlist are wonderful, and easy to follow. I have seen nothing there I would not tackle myself as a "junior gearhead".
I think they might could have done more "in depth" on diagnosis rather than just changing out parts-- but its good stuff.
If you have not seen this resource here is the link. I had not been willing to tackle repairs on my jacks and slides, but now I am. Its a link I will treasure, saved and always have access to as long as i have an internet connection! I hope they post more along these lines.
