No lubrication? Makes me wonder if this video put out by Lippert on how to lube it is no longer valid: https://www.youtube.com/watch?v=8KbVRFMo1Rg
Engine running before extending slides? My Thor product has an interlock that prohibits me from doing that.
I am glad that yours is working better now. It is amazing how much contradictory information is out there about these slides. I hope that the foot dip is an overstatement. I can't imagine it having that much play without breaking something. My slides to tip a little when the CG of the slide passes over the rollers. They lean out when the slide is out and in when the slide is in but maybe 1/4 of an inch is all. The big problem with mine was that the rack was not shimmed properly at the factory and only had about 25% tooth engagement so the teeth wore out quickly. After several attemps at a field repair I had to drive it back to the factory to get it done right. I just don't know why it was not done right the first time. At least Thor did compensate me for some of my driving expense and were very helpful while I was there.
