Hi, If yours is a year 2000, odds are pointing more to the Barker unit. A year or more newer and the Lippert unit came into play
What you are describing about one side of the slide being 2 1/2" short of coming in all the way points to: (this would be for the Barker unit)
Can be any of these or a combo of them
1. Slide drive jumped time. Odds are low it jumped teeth however shearing a pin in the drive shaft to the pinion gear or at the motor drive very possible. Look to see if the drive shafts have all the bolts or pins in place.
2. At the end of the slide arms is generally some type of slotted adjustment where it attaches to the slide itself. If the slot slipped you may see rust witness lines. If slipped, then once you get it out, jack up the slide gently, put jack under outside slide wall, take just enough weight off to lift a 1/8". Then loosen the bolts over the slot and shift the slide. Floor jack on concrete works best as the jack rolls with the slide.
3. One of the arms bent. Odds are low, but confirm with a straight edge.
If you cannot find it, get a helper and position yourself from the opposite side of the camper, (non slide side) bend down and look from a distance (6 to 8ft away) at the slide drive shafts. Have the helper just jog the motor. Are both shafts turning and then are both sprockets turning? If a pin or bolt sheared you can see which one is not turning. If one side is sheared, the slide will be in a bind trying to move and not go out.
Hope this helps. Glad to yak more as needed. Good hunting
