Slide I.D.

I have a new to me 2005 Terry 290rls Quantrum.Have all the manuals
except the one for the slide.After 13 years with Prowler with a
cable oper. slide I have no idea what this one is.It has a bar with
teath at each end.Another bar to make adjustments and a sheet metal
u shape arm that has all the electric wires that folds as the slide
goes in and out.If some one can tell me what it is and model #
I can start looking for a owners manual.

THANKS TO ALL
