Stabilizer Jack Grease
We just bought a brand new Jayco Whitehawk. I asked the head of service what to use to lube the slide gears and jacks and he said WD40. This sounded really cliche but he said it doesn’t attract dirt and should be a regular part of maintenance. I will probably try it on two of the jacks, and crc power lube on the others and make a choice from there.
