According to the Lippert manual:
No grease or lubrication is necessary and in some situations may be detrimental to the environment and long term dependability of the system.
You can find manuals on all Lippert components at http://www.lci1.com/index.php?option=com_content&view=article& id=54&Itemid=66
IMHO a CW tech would be the last person I'd take advice from
I never use any lube as it only attracts dirt.... even the "dry" try.
