It explicitly states "Do not lubricate rack and pinion gear teeth, simply the 4 spots on the drive shaft only".
Naturally, Camco and other manufacturers advertise the "slide spray lubricant" as the way to go.
I guess since Lippert says "NO", I have been misguided in spraying the rack and gear all these years?
That info is on page 12 on the manual. I don't know that there's necessarily a conflict. Normally, they say no maintenance is required. The info on page 12 about oiling is titled "Corrective Action for Squeaking Gear Packs." So my take on it is, if it isn't squeaking, don't oil or lube it. But if it does start squeaking, here's how to oil it.
I do agree that any type of lube that's going to attract dust/dirt will only make it worse -- especially if it's attracting in onto the hydraulic rod.
