Today after sitting for almost 5 months I moved the slides in and out in preparation for leaving Friday.
The rear slide seemed sticky, it wasn't smooth and made kind of like a groaning sound. The second time I operated it it moved smoother but still made a slight groaning sound. This slide has the raised floor and has a box under the bed that I assume is for the slide mechanism. I haven't removed that cover yet but probably will tomorrow.
Are there any points that need to be lubed?

Forest,
I've been told there is nothing to lubricate. You do want the boom to be clean. Maybe what you heard were the slide seals sticking???

Possibly Steve, but we did clean the sides with WashnWax before operating them. It did seem smoother after a couple times.
