I have a 2002 Fleetwood Fiesta 32S and the main room slide slips while moving out (we put manual pressure to get it to go out), comes back in fine. I have been told the system was originally manufactured by RBW Industries, then sold to Al-Ko Kober. Somewhere along the way it has been sold several times to possible Power Gears and/or Dexter Axle?? Does anyone have any way to find the specs to have this gear box rebuilt locally at a machine shop or a suitable replacement for the gear box. Part number could be either GS0-23364 or GS0-0281 (I was told both of these numbers by two different vendors). I have been told this piece is obsolete. Any help would be appreciated. (I have reached out to Fleetwood, waiting for a reply).
