Dry lube only, if you use any kind of grease on the track it will pick up dirt a destroy the gear. Slide the slide out all the way and clean the track of any metal filings from the track. I found a lot when I purchased mine new. Also my rubber seals and track we're not lubed from new so do this ASAP .
Forest River uses 3-4 different slide systems. My old trailer used hydraulics where my new trailer is electric. Ask your dealer which lube is required for your trailer.
