No pics, but it looks like a Reese 16k Kwik-Slide (since that's what it is...) No rails, just the slider and the 16k head. Used maybe half a dozen times by a friend of mine and stored indoors. Looks practicallly new. I bought it to put in my truck but have since found another hitch that suits my needs better. $300 takes it, if I have to ship then you pay actual charges. It's heavy so shipping won't be cheap. I can palletize it and ship from a loading dock in 95054. It probably weighs somewhere around 200 lbs.
I found a standard Reese 16k that comes with the rails for the same price. Not exactly what I want, but at least it's not a slider. A slider in a longbed just strikes me as cheesy so I prefer a standard unit.
Yup, I still have it. I had one sale fall through because shipping costs were ridiculous and I haven't posted it back up again yet.
