Who is schooled in "Grease"? (Need some tough stuff)

Slightly off-topic, but this reminds me of a conversation I had with a fellow RVer recently. He told me he had to replace the stabilizers on his new RV because they'd seized up. The owner's manual cautioned they should not be greased though. So he called the factory and they told him he should have followed want the manual said, which he'd done and so indicated. They checked the manual then came back and told him, "Oh, the manual should have stated to use dry lube on the stabilizers, not grease."
