Service manual for 5th wheel hitch

I seldom use the slider of my slider but I keep a can of WD-40 in the truck and will spray it on the rails and rollers when I do use them. I keep a light coat of grease on the head pivots, lock bar, and retaining bolts, Generally, I try to keep it dry and clean without being a fanatic about it. I do also wash the whole thing with a power washer in the spring before I put it back into the truck.
